[Octave-bug-tracker] [bug #31931] figure (1, "visible", "off") -> Bus error

[Søren Hauberg]

Follow-up Comment #20, bug #31931 (project octave):

I don't know the code well enough to have say if your patch is correct or
not. It seems like some OpenGL implementations don't care if a GL context is
available, while others crash if one is not. At least my version of FLTK seems
to only create a context when we call 'Fl_Window::show ()', which means that
the current code is bound to crash when working with invisible figures.

I came up with the attached patch which fixes things for me. It is quite
similar to the ones suggested by JWE. However, as I said I don't know the code
well enough to make an informed decision here :-(
