[Octave-bug-tracker] [bug #44330] Qt toolkit segmentation fault when figure opened, closed, and opened again

[Rik]

Update of bug #44330 (project octave):

                  Status:         Patch Submitted => Confirmed

Follow-up Comment #11:

Re-running the original example code I now occasionally get more error
messages when the segfault occurs.  See below


octave:5> h = figure (); close (h); h = figure ();
octave:6> pure virtual method called
terminate called without an active exception
panic: Aborted -- stopping myself...
attempting to save variables to 'octave-workspace'...
save to 'octave-workspace' complete
Abort


Interestingly, it seems that Octave has returned to the command prompt before
something else goes wrong.

More confirmation that there is some sort of race condition, the following
code works


h = figure (); close (h); pause (0.1); h = figure ();


But it is possible to make the delay short and then the segmentation fault
returns.  For example, a delay of .01 fails for me.
