I'll close it for now and we can see if we get further reports.

Dear Rik,
I've bisected the failed test the last days. I always did a fresh, out of source, build (run ./bootstrap before in src) and my configure call was "../octave-src/configure --disable-java --disable-docs --disable-gui". After that make -j8

The last steps were:

So for me it looks like the merge from stable to default caused the problem on my system.

If no one else sees this failed test or can reproduce the problem we can close this report if you want.

Are you suggesting that cset b14cdae65abd introduced the test failure, or only that this was the latest version you happened to compile that shows the problem?

Since you have access to Mercurial, what happens when you go back to the 3.8.0 release tag

Do the failures begin with the 3.8.0 release or are they even earlier?

This works for me on Mint 13 (equivalent to Kubuntu 12.04) and libcholmod 1.7.1 with an Intel Core2Duo.

Debian wheezy, libcholmod1.7.1

"make check" after build of b14cdae65abd (stable) reports for dldfcn/chol.cc-tst

ASSERT errors for: assert (cca' * cca,ca,16 * eps)
Location | Observed | Expected | Reason
(3,3) 16+5.5511e-17i 16 Abs err 3.5531e-15 exceeds tol 3.5527e-15

I can reproduce this on 2x AMD Phenom II X6 CPUs and 1x AMD Athlon(tm) 64 X2 all with with Debian wheezy (stable).

Anything else I can test?
