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

[Dmitri A. Sergatskov]

Follow-up Comment #27, bug #44330 (project octave):

If I add a short pause() between delete(c) and delete(f) then it works fine:


 octave:1> f = figure; c = uicontrol( 'parent', f, 'string', 'button' );
delete(c); pause(0.1); delete(f)
octave:2> 

But for short pause it still crashes:

octave:1> f = figure; c = uicontrol( 'parent', f, 'string', 'button' );
delete(c); pause(0.01); delete(f)
octave:2> warning: base_graphics_object::get_properties: invalid graphics
object
terminate called after throwing an instance of 'std::bad_cast'
  what():  std::bad_cast
Aborted (core dumped)


Dmitri.
