[Octave-bug-tracker] [bug #48669] Segfaults at exit after using OpenGL-based toolkits in --no-gui mode

[Dan Sebald]

Follow-up Comment #3, bug #48669 (project octave):


octave:1> graphics_toolkit ('fltk')
octave:2> sombrero ()
panic: Segmentation fault -- stopping myself...
attempting to save variables to 'octave-workspace'...
save to 'octave-workspace' complete
Segmentation fault


OK, Qt then:


octave:1> graphics_toolkit ('qt')
octave:2> sombrero ()
octave:3> get (gcf (), '__gl_version__')
ans = 3.3.0 NVIDIA 340.96
octave:4> get (gcf (), '__gl_vendor__')
ans = NVIDIA Corporation
octave:5> get (gcf (), '__gl_renderer__')
ans = Quadro FX 4600/PCIe/SSE2
octave:6> exit

panic: Segmentation fault -- stopping myself...
Segmentation fault


Oh hey, pretty neat functions.  So my new OS is using the graphics card for
rendering, no wonder rotating plots are so much faster now.

Well, I could try Nouveau or Gallium, but they are a bit of work to build. 
Maybe I can try debugging for the Nvidia driver as well with some trial and
error.
