Follow-up Comment #7, bug #61742 (project octave):
Thanks for that link, but it didn't work in my case. I don't have avx512
either, only avx and avx2 (Zen 2). I spent this evening changing various flags
for building OpenBlas. In all the cases where the library could be built, it
passed all the tests including the extra tests for thread safety. On running
the OpenBlas benchmarks, they are able to handle dgemm for 200x200 with no
problem, but somehow when called from Octave for any Matrix above 64x64 it
causes a segfault on exit.
This is not a show stopper but it's a nuisance because it is repeatable but
not universal. It means if a script is calling Octave and then examining the
exit value it will conclude failure because of the crash on exit. But it is
not clear why this happens at all.
The only hope is that enough others might have it that there's a fix,
otherwise I'll simply have to downgrade OpenBlas.
