Follow-up Comment #1:

Thanks for your bug report. Confirmed, the segmentation fault is in the Qt
graphics_toolkit library. If "graphics_toolkit fltk" is used instead there is
no segfault.

The following is enough to make the segfault occur for me. The commands have
to occur on a single line, no return to the prompt to allow background events
to be processed. Or the commands have to occur in a single script without any
pause between them.


graphics_toolkit ("qt");
h = figure (); close (h); h = figure ();
