CSParse, CXSparse, SPQR are all parts of SuiteSparse.
SPQR is described in T. Davis paper:
http://dl.acm.org/authorize?6504334
(it is also included in SuiteSparse docs).
Most of Suite sparse libraries are described in T.D. pub at:

Good analysis. One question, is it always the case that the inserted rows can safely be deleted? In the example we are using, the R matrix has three fully empty rows between the last row with an entry at (2,2) and the next entry at (6,6). Collapsing null rows is a fairly easy operation and if the entry at (6,6) were moved to (3,6) everything would work out correctly.
Second, Tim Davis, author of SuiteSparse has moved from the U. of Florida to Texas A&M. The overview page for SuiteSparse is now at http://faculty.cse.tamu.edu/davis/suitesparse.html. According to this page, Matlab has moved QR to rely on the SuiteSparse library. Given that Octave already uses SuiteSparse in some capacity, maybe we should just switch to a different library. Is there a comparison table between CSparse, CXSparse, and SuiteSparse in terms of things like memory usage, efficiency, speed, etc.?

From what I can tell, Octave doesn't call cs_qr_mex. However, it appears to parrot how that file is constructed. For example, the comments in sparse-qr.cc about whether or not the double transpose to sort is necessary. This double transpose can also be found in cs_qr_mex.c. That said, I don't know the history of the files, so I don't know for sure.
Anyway, it looks like a number of things are going on that are simultaneously breaking. At its core, though, it's not clear to me that cs_qr can correctly compute what Octave currently asks for it. As I mentioned before, p78 of Tim Davis' book Direct Methods for Sparse Linear Systems notes that extra rows can be added when the matrix is structurally rank-deficient. For how he calls the routine, this isn't too much of a problem since he generally doesn't form Q. Rather, he keeps around the Householder reflectors and then uses them. In that way, it doesn't really matter if the extra rows are there because if we solve when the factorization we can always remove the extra zeros from the solution later. In our case, this doesn't work since we want Q.
The easiest way to see why is to use cs_qr_mex.c from CXSparse along with cs_qright. Also, comment out the row/column check in cs_qr_mex.c to make this simpler:
//if (m < n) mexErrMsgTxt ("A must have # rows >= # columns") ;
Anyway, we can ask CXSparse for the QR factorization with the following code:
% Create the matrix
A=sparse(5,6);A(3,1)=0.8;A(2,2)=1.4;A(1,6)=-0.5;
% Find the factorization
[V beta p R q]= cs_qr(A);
% Find Q
Q = cs_qright(V,beta,p,speye(size(V,1)));
Here, we get:
octave:6> full(Q)
ans =

Or really:
R =
Compressed Column Sparse (rows = 8, cols = 6, nnz = 3 [6.2%])
(1, 1) -> -0.80000
(2, 2) -> -1.4000
(6, 6) -> 0.50000
This is where we see the element in the (6,6) position. Notice, that these matrices are much bigger than what we want. We want Q to be 5x5 and R to be 5x6, but we added three rows. Now, I believe the current QR factorization code in Octave just truncates these matrices. Note:
octave:107> [qqq rrr]=qr(A)
qqq =
0.00000 0.00000 0.00000 -0.50000 0.00000
0.00000 -1.00000 0.00000 -0.50000 0.00000
-1.00000 0.00000 0.00000 -0.50000 0.00000
0.00000 0.00000 0.00000 -0.50000 0.00000
0.00000 0.00000 0.00000 -0.50000 0.00000
rrr =
Compressed Column Sparse (rows = 5, cols = 6, nnz = 3 [10%])
(1, 1) -> -0.80000
(2, 2) -> -1.4000
(6, 6) -> 0.50000
This is bad for two reasons. One, the (6,6) element can't exist in a 5x6 matrix. Two, we have an all zero column in Q, so Q is not unitary (Q'*Q=I).
Now, can this be fixed? I'm really not sure. We can't safely truncate R since adding additional rows may very well mean that nonzero elements are pushed into the extra rows in the factorization. Without changing the algorithm, I'm not sure this can be prevented. Again, if we don't need Q, this is not necessarily a problem since we can still solve linear systems using the Householder reflectors directly and then truncate the result. However, there are situations where we want Q.
One possible, bad, fix is to play a game with a Dulmage-Mendelsohn permutation of R. Basically, the DM permutation permutes things to try and obtain a block diagonal structure. We know that we should have this in R, so it should be safe to use. For example, the following code kind of fixes cs_qr_mex:
% Computes the QR factorization in a slightly odd way that sort of handles
% structurally rank deficient matrices.
function [Q R]=myqr(A)
% Determine the size of the matrix
[m n]=size(A);
% Find the QR factorization
[V beta p R q]= cs_qr(A);
% Find Q
Q = cs_qright(V,beta,p,speye(size(V,1)));
% Find the Dulmage-Mendelsohn permutation of R
[p q]=dmperm(R);
% Reorder the rows of R and the columns of Q. The goal here is to move the
% elements of R up in the case where it's structurually rank deficient
% while keeping the block diagonal structure.
Q=Q(:,p);
R=R(p,:);
% Truncate the size of Q and R
Q = Q(1:m,1:m);
R = R(1:m,1:n);
end
For example, if we try the code:
% Create the matrix
A=sparse(5,6);A(3,1)=0.8;A(2,2)=1.4;A(1,6)=-0.5;
% Find the factorization
[Q R]=myqr(A);
We get:
octave:2> Q
Q =
Compressed Column Sparse (rows = 5, cols = 5, nnz = 3 [12%])
(3, 1) -> -1
(2, 2) -> -1.0000
(1, 3) -> -1
octave:3> R
R =
Compressed Column Sparse (rows = 5, cols = 6, nnz = 3 [10%])
(1, 1) -> -0.80000
(2, 2) -> -1.4000
(3, 6) -> 0.50000
which is almost what we want. Basically, the R matrix now looks good, but Q is messed up. Note, Q is not unitary and has zero columns. However, here, A=QR. Anyway, it works because it essentially replaces the old factorization A=QR with A=QP'PR where P is a permutation designed to move everything above the added rows. I think this would be better than what Octave currently does, but it's not a great solution.
Likely a better solution would be to migrate the code from CXSparse to SPQR, which uses a different algorithm where this isn't an issue. I believe MATLAB already uses SPQR; it's faster; and Octave is already using codes from SuiteSparse.
Anyway, if someone has an easier solution, I'd like to hear. Thanks for taking a look at things.

@Joseph: if I understand it correctly, octave calls the cs_qr_mex file and the result is wrong, while a direct call to the library (last part of your comment, in which it should be R(3,6) = -0.5 and not R(6,3) = -0.5) would give the right result?

This is likely an issue inherited from the original cs_qr_mex file. This call is a little wonky:
octave:2> A=sparse(5,6);A(3,1)=0.8;A(2,2)=1.4;A(1,6)=-0.5;
octave:3> [V beta p R q]= cs_qr(A)
error: cs_qr: A must have # rows >= # columns
If we add the additional row to force it to work:
octave:4> A=[A;sparse(1,6)]
A =
Compressed Column Sparse (rows = 6, cols = 6, nnz = 3 [8.3%])
(3, 1) -> 0.80000
(2, 2) -> 1.4000
(1, 6) -> -0.50000
octave:5> [V beta p R]= cs_qr(A)
V =
Compressed Column Sparse (rows = 9, cols = 6, nnz = 6 [11%])
(1, 1) -> 1.6000
(2, 2) -> 2.8000
(3, 3) -> 1
(4, 4) -> 1
(5, 5) -> 1
(6, 6) -> -1
beta =
0.78125

R =

(1, 1) -> -0.80000
(2, 2) -> -1.4000
(6, 6) -> 0.50000
Notice that we have the magical (6,6) element. However:
octave:6> [q r]=qr(full(A))
q =
0 0 1 0 0 0
0 1 0 0 0 0
1 -0 0 0 0 0
0 -0 -0 1 0 0
0 -0 -0 -0 1 0
0 -0 -0 -0 -0 1
r =
0.80000 0.00000 0.00000 0.00000 0.00000 0.00000
0.00000 1.40000 0.00000 0.00000 0.00000 0.00000
0.00000 0.00000 0.00000 0.00000 0.00000 -0.50000
0.00000 0.00000 0.00000 0.00000 0.00000 0.00000
0.00000 0.00000 0.00000 0.00000 0.00000 0.00000
0.00000 0.00000 0.00000 0.00000 0.00000 0.00000
Candidly, it shouldn't be there. What's happening? Other than cs_qr_mex.c likely having a bug, there is documentation in cs_qr.m:
If A is structurally rank deficient, additional empty rows may have been added to V and R.
In other words, CXSparse can and will add additional rows to R when it deems fit. This is discussed on page 78 in Tim Davis' book Direct Methods for Sparse Linear Systems:
The cs_qr function uses the symbolic analysis computed by cs_sqr: the column elimination tree S->parent, column preordering S->q, row permutation S->pinv, the S->leftmost array, the number of nonzeros in R and V (S->unz and S->lnz, respectively), and the number of rows S->m2 after adding fictitious rows if A is structurally rank deficient.
Here's an example of the call in C:
#include "cs.h"
int main() {
// Create a 5x6 matrix with a max of 10 values. Allocate memory for the
// values and denote that we're using triplet form.
cs * A = cs_spalloc(5,6,10,1,1);
// Set the entries of A
cs_entry(A,2,0,0.8);
cs_entry(A,1,1,1.4);
cs_entry(A,0,5,-0.5);
#if 1
cs_entry(A,0,2,0.0);
cs_entry(A,0,3,0.0);
cs_entry(A,0,4,0.0);
#endif
// Convert A to a compressed matrix
cs * Ac = cs_compress(A);
// Perform a symbolic QR factorization of A. The 0 means natural ordering
// and the 1 means we're doing a sparse qr factorization.
css * As = cs_sqr(0,Ac,1);
// Perform a QR factorization of A
csn * QR = cs_qr(Ac,As);
// Free memory from A and Ac
cs_spfree(A);
cs_spfree(Ac);
// Free the symbolic factorization
cs_sfree(As);
// Free the QR factorization
cs_nfree(QR);
}
In gdb we can see:
(gdb) print QR[0].U[0]
$4 = {nzmax = 3, m = 8, n = 6, p = 0x100203550, i = 0x100203580,
x = 0x100203320, nz = -1}
(gdb) print QR[0].U[0].p[0] @ 7
$5 = {0, 1, 2, 2, 2, 2, 3}
(gdb) print QR[0].U[0].i[0] @ 3
$6 = {0, 1, 2}
(gdb) print QR[0].U[0].x[0] @ 3
$7 = {-0.80000000000000004, -1.3999999999999999, -0.5}
In other words, we have
R(1,1) = -0.8
R(2,2) = -1.4
R(6,3) = -0.5
which is what we want except for that R has size 8 x 6 since CXSparse added 3 fictitious rows since we were structurally rank deficient.
How do we fix this? Unless I'm missing something, I can't seem to find a routine in CXSparse that drops the fictitious rows automatically. We can probably just calculate the size by hand and ignore what comes out in the cs matrix since the number of rows may be greater than what we want.

Unfortunately, it doesn't seem to be the sorting. I commented out the sort code and then re-ran the example
So the extra zeros are not dropped, but the problem remains at location (6,6).
Maybe we aren't calling QR correctly, or we've discovered some weird longstanding bug in the library. Someone who understands the CSPARSE library needs to help out here.
The call is at line 208 of sparse_qr.cc

The code in question is at line 271 of sparse-qr.cc
I used gdb to step through the code and display ret before it is returned.
So it is the output of the library code in N that is the problem. I don't know if we are not feeding the QR factorization the right values, or whether it is this sort routine that is the problem

I tested some old versions of Octave with Marco's test case and the problem exists all the way back to Octave 3.2.4, and probably before that as well but I don't have any earlier versions.
The code is in liboctave/numeric/sparse-qr.[h|cc]. This doesn't appear to be a problem with the full version which is in liboctave/numeric/qr.[h|cc].
I tried the full version
The difference is element (3,6) which is missing in the sparse version

@Mike, I found a similar example
so an extra element in position (6, 6). If you run qr on full(A), you discover that the element 0.50000 should be in position (3, 6).

Wed 06 Sep 2017 07:23:28 PM UTC, comment #5:
Marco - I agree, I think the matrix has to be the result of a QR factorization.
In particular, qr may return an R matrix that is malformed, that has entries that are out of bounds. For example
Notice the size of the matrix R is 5×6, but it has an element at index (6,6). This matrix crashes the subsequent qr(R) because it contains an element that is out-of-bounds.
So the real bug here is that qr may return an R matrix with an element like this shown above. I don't have the knowledge of the algorithm or the libraries involved to dig further at the moment, someone want to look into this?

It seems that r has to be the result of a qr factorization and not a simple upper triangular rectangular matrix with some zeros on the diagonal. Strange.
