Follow-up Comment #6, bug #68434 (group octave):

You CPU is newer than your OpenBlas. OpenBlas has a dynamic dispatcher that
tries to figure out the CPU type. Most likely it thinks that your CPU has
AVX512 instructions and that causes the crash. That normally would cause
signal 4 (SIGILL) though...
Anyway, you can try to start octave as:
+verbaatim+
$ OPENBLAS_CORETYPE=HASWELL octave
-verbatim-
and see if that helps.
If it does you can set this variable in your shell startup files.

Dmitri.
