I’m using Debian unstable, XFree86 4.2.1 with Matrox G400 (DRI drivers).
I created a really simple opengl-app, which of course works just fine. Now, when I add glew (http://glew.sf.net, opengl extension handler library) to the project, SDL starts to segfault! Note that I don’t use glew at all, just linking glew.o to the the executable causes SDL to segfault!
Segfault happens in SDL in X11_GL_Shutdown() when this->gl_data->glXReleaseBuffersMESA() is called.
Any ideas how glew can make glXReleaseBuffersMESA() to crash the whole program? Note again that I don’t use glew at all! I just link with it!
The program is available for testing from http://nrg.joroinen.fi/sdl-glew-bug.tar.gz
Please test & comment! Note that the crash only happens with Mesa-based drivers (There’s no such function in Nvidia’s drivers).
I really would like to get this solved, because glew rocks (not counting this bug…)
