[Octave-bug-tracker] [bug #61393] [octave forge] (sparsersb) Crash while "pkg test sparsersb"

[Markus Mützel]

Follow-up Comment #2, bug #61393 (project octave):

I attached gdb to Octave 7.2.0 on Windows and ran the command `pkg test
sparsersb`.
The top of the backtrace from the resulting segmentation fault:

Thread 25 received signal SIGSEGV, Segmentation fault.

Does that give a clue where you could add a check that could avoid the
segmentation fault?
