I'm trying to debug some OpenGL "invalid operation" in my pyglet code. On
OS X the best (and possibly only) option is the OpenGL Profiler that can be
found in the Xcode Graphics Tools. This works fine for other OpenGL apps
(I've tried VLC), but when I configure it to launch my pyglet code, Python
crashes while trying to create the CoreGL context (see dump below). Any
idea what's going wrong here and how to fix it? This does not happen when
launched outside the profiler, but obviously something goes wrong with the
combination of profiling and pyglet.
