[Octave-bug-tracker] [bug #54656] Crash with signal 11 (segfault)

[Mike Miller]

Follow-up Comment #4, bug #54656 (project octave):

This looks very similar to the crash reported in bug #54431. The bug there
looks like a simultaneous access to the symbol table while a script is running
and the workspace view is being updated.

jwe - did you test with 4.4.1 or 5? Because a recent change on the default
branch made it so that the workspace view is *not* updated when a script calls
the 'clear' command. That might be what is triggering the crash in this
script. It would be useful to see if the script crashes in 4.4.1 but not in 5
because of that.

But that doesn't mean the underlying bug is fixed. As I posted on bug #54431,
the crash can still be triggered by entering debug mode and rapidly stepping
through the script by holding down Enter, which does cause a workspace view
refresh on every prompt.
