That stack trace can't be valid. __glXPopArrayState() is an internal libGL function that almost certainly is not called from the app's osg::Geometry::drawImplementation() function. I don't see any way that __glXPopArrayState() can call itself either. I think you'll need to use a libGL compiled with -g to get a good stack trace. Alternately, you might try running with valgrind to see if something funny is going on elsewhere (very likely).
