Details:

I suddenly observe very frequent segfault when opening figures - I would say
this is related to a change in dev over the last week or so.

At the moment, running this:


F    = figure(...
    'Position',[659 20 767 1105],...
    'Visible','off');
figure(F)


results in this:


>> testfigure
>> panic: Segmentation fault -- stopping myself...
attempting to save variables to 'octave-workspace'...
save to 'octave-workspace' complete
Segmentation fault


or sometimes the figure becomes visible and unresponsive - Octave has to be
killed.

It even seems that running something as simple as this:


figure('position',[659   200  767   421])


creates an unresponsive figure. If the 'position' property is not set up, it
works as usual.
