[Octave-bug-tracker] [bug #61742] Crash on exit from threading

[Arun Giridhar]

Follow-up Comment #11, bug #61742 (project octave):

I solved the problem. It turned out the distro was automatically adding
"USE_TLS=1" to the OpenBlas settings, which stands for "thread-local storage"
as opposed to a central memory buffer. That setting alone was responsible for
the segfaults on exit. Removing that setting solved the problem.

Now there is no crash on exit:

octave:1> version -blas
ans = OpenBLAS (config: OpenBLAS 0.3.19 NO_AFFINITY USE_OPENMP ZEN
MAX_THREADS=12)
octave:2> a = randn(5000); tic; inv(a)*a; toc
Elapsed time is 2.29698 seconds.
octave:3> 
octave:3> exit


This probably affected anybody using Arch or Manjaro or other Arch-derived
distro. The solution is to remove USE_TLS.
