[Octave-bug-tracker] [bug #48669] Segfaults at exit after using OpenGL-based toolkits in --no-gui mode

[Dan Sebald]

Follow-up Comment #11, bug #48669 (project octave):

As for the seg-fault at exit for both FLTK and Qt, I wonder if there needs to
be a glFinish() somewhere before leaving the main application.  glFinish() is
like an OpenGL flush that waits until all OpenGL commands currently queued for
OpenGL are finished.  Could it be that there is a race condition at exit
between the application quitting and Qt/FLTK or some other OpenGL stuff to be
processed?  Again, I'm not an OpenGL expert.
