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

[Rik]

Follow-up Comment #15, bug #44330 (project octave):

How does atomic refcounting relate to this discussion?  Is that only
protecting data structures against being deleted in either the plotting thread
or Octave while the other might be using it?  I suppose if we have atomic
access then we could set up a global semaphore to prevent the plotting thread
from proceeding until given permission by Octave.  It would be nicer if we
didn't have to code that ourselves though.
