Creating the figure window works (i.e. issuing the co= mmand "figure" doesn't cause the crash, it is only when plotting within the= figure that I get a crash). I use the Octave command "sombrero" to test th= e plotting of data, but even simpler commands ("plot(1:10,1:10);") cause th= e crash. The crash occurs whether using the fltk or qt graphics toolkit. I'm using: Octave: GNU Octave, version 4.0.1 Cygwin: CYGWIN_NT-6.1-WOW OEM-9D7L362 2.5.0(0.297/5/3) 2016-04-11 09:55 i68= 6 Cygwin The command I issue in Octave is: >> sombrero And I get this error message: >> panic: Segmentation fault -- stopping myself... attempting to save variables to 'octave-workspace'... save to 'octave-workspace' complete I ran strace to try to debug the problem. The strace output is too large (M= B) to attach, but comparing strace for a normal termination of octave (run = octave, create a figure but without plotting) and a segmentation fault term= ination of octave (run octave, issue command "sombrero"), I see that a segm= entation fault causes "threads exited with status 0xc0000005". However I do= n't know how to debug this any further. I attach the output of cygcheck -s -v -r=20 Any suggestions on how to debug this further or how to fix it would be very= welcome! I have tried downgrading octave and qt but to no avail.
