[Octave-bug-tracker] [bug #57245] "clear all" generates segfault if run before or after a plot

[Carlo de Falco]

Follow-up Comment #8, bug #57245 (project octave):

If nobody with other OSes is seing anything similar this must be a mac
specific issue.

Can anyone else with a mac confirm the same issue?

In the meanwhile, I think I managed to run Octave within lldb to get a
backtrace of the crash:
