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

[John W. Eaton]

Follow-up Comment #14, bug #44330 (project octave):

Yes, maybe.

I'm almost certain that the crashes are happening because of threading issues,
and that we are calling Octave internals from the graphics thread when it is
not safe to do so.  If this wasn't an issue with the original QtHandles code,
then maybe there was some change that was made since integrating it with
Octave that allows unsafe calls where none were possible before.  If so, we
need to know how to avoid doing that.  If it's just that were were lucky
before, then we need to rethink the design.
