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

[Carlo de Falco]

Follow-up Comment #11, bug #57245 (project octave):

actually, by running in the source directory rather than from installation
directory I do see source code references in lldb

here's what I get with 'clear all; plot (randn (5))'
