Follow-up Comment #16, bug #47914 (project octave):
That error might be caused by the current implementation of lights. On one of
my systems, the constant GL_MAX_LIGHTS is way too high. I am not sure what
happens in the following lines when "i" increases way too far:
// disable other OpenGL lights
for (int i = num_lights; i < GL_MAX_LIGHTS; i++)
glDisable (GL_LIGHT0 + i);
A fix for this is contained in file #37999 in patch #8943.
It might also be completely unrelated but comment #14 rang a bell to me.
