[Octave-bug-tracker] [bug #46038] Crash when uicontrol's callback returns an error

[Rik]

Follow-up Comment #5, bug #46038 (project octave):

Interestingly, I can no longer trigger this bug if I use jwe's experimental
re-write of the core to use exception handling for errors.  I posted about my
success on the maintainer's list and I think it very likely that he will
commit his patch to core shortly.

If you want to see if it works for you I've attached the patch to this report.
 You will need a working development build tree.  Then,


# In source tree
patch -p1 < exception-error-diffs-v3.txt


The exact sequence I used to produce the error before the patch was


run-octave -f
F = figure;
h = uicontrol(F,...
  'Style','Pushbutton',...
  'String','OK',...
  'Callback',"error('err')");

# Click on OK button
# Click on Canvas object (center of window)
