[Octave-bug-tracker] [bug #58814] Abort, core dump on exiting from graphics code

[Markus Mützel]

Follow-up Comment #7, bug #58814 (project octave):

I tried to test what Matlab R2020a is doing when cleaning up figures on exit
with this script:

hf = figure('DeleteFcn', @createOnDelete);

function createOnDelete(~,~)
  figure('DeleteFcn', @createOnDelete);
end


Using "diary" wasn't really helpful because it seems to close quite early on
when exiting.
Instead I'll try and describe what I see on screen:
- When executing the script, an empty figure is displayed.
- When I then close Matlab, that figure closes followed by a new figure that
appears on screen.
- After that the main GUI window of Matlab disappears (almost) at the same
time as that new figure disappearing.
- A short time after, yet another figure window flashes on screen for the
fraction of a second.
- Matlab does *not* hang around as a ghost process but seems to have closed
successfully.

I don't think we *need* to follow exactly what Matlab is doing here. Just
meant as a point of reference.
