Follow-up Comment #18, bug #48186 (project octave):
The problem seems to be that at some point "allchild" returns handles that
"ishghandle" judges invalid:
F = figure('Units','normalized');
h1 = uipanel(F,'Position',[0 0 0.45 1], 'DeleteFcn','disp (ishghandle
(allchild (gcbf ())))');
h2 = uipanel(F,'Position',[0.55 0 0.45 1]);
close (F);
This shows that the first handle in the return list (h2) is not valid anymore.
