[Octave-bug-tracker] [bug #41244] Segfault using the figure() command

[Michael C. Grant]

Follow-up Comment #5, bug #41244 (project octave):

I'm honestly not surprised. I certainly understand that debugging these things
is not trivial. There's a reason, I'm sure, that the Mac binary builds use
gnuplot!

If it's remotely useful to anyone, if I quit before a segfault, I often get
this assertion error:
