Thanks for testing again (and for checking this in the first place).

I'm also not sure about the results of `test memory`. But let's assume that the address sanitizer somehow influences the return values of the system functions we use. That might lead to those values being interpreted as inconsistent. (I guess "innocent until proven guilty" in this case.)

Closing as fixed.

It goes through make check with "memory" check failing (probably OK, I assume asan messes things up there):

octave:1> test memory
***** testif ; (isunix () && ! ismac ()) || ispc ()
 [user, syst] = memory ();
 assert (user.mem_used_octave > 0);
 assert (user.ram_used_octave <= user.mem_used_octave);
 assert (user.mem_used_octave < syst.SystemMemory.Total);
 assert (user.MemAvailableAllArrays <= syst.SystemMemory.Available);
!!!!! test failed
assert (user.mem_used_octave < syst.SystemMemory.Total) failed
octave:2> [user, syst] = memory ();
octave:3> user.mem_used_octave
ans = 2.1995e+13
octave:4> syst.SystemMemory.Total
ans = 7.7062e+10

That change has been missing from a new feature that was added on the default branch. (I missed that when reviewing that patch.)
Pushed the change from comment #7 here:

Yes. This fixed lsode problem. Running make check now.

IIUC, `m_iwork` is initialized to the `nil_rep`. Indexing it will probably fail.

Does this change fix the issue from comment #4 and #5?

This particular case:

I passes this instance, but now crashes at lsode.cc-tst:

I haven't pushed any of my changes to create the release so I could go back and insert this one small change and repackage the release.

Thanks for the report.

It looks like `dim_vector::redim` is used discarding the result.
Does the following change fix it for you?

It's probably too late for Octave 7.3. But it'd probably be worth to fix on stable anyway.

The actual crash has nothing to do with bsxfun.
