[Octave-bug-tracker] [bug #47400] panic on Ctrl+c with multithreaded ATLAS or OpenBLAS

[Rik]

Follow-up Comment #7, bug #47400 (project octave):

For easy testing, I have uploaded a script called tst_ctrlc.m.

Steps to produce a segfault:

1) Run octave
2) tst_ctrlc
3) Type Ctrl+C

Segfaults every time for me regardless of whether I am running Octave in the
GUI or at the command line.

A workaround is to use


setenv OMP_NUM_THREADS 1


which stops multiple threads in the OpenBLAS library.
