rev 473 segfaults on debian with Intel 965 graphics

I just svn updated and recompiled, now q2w crashes. I'm quite sure it's due to a bug in the intel graphics driver though...

This is what happends:


spirit@threat:~/share/builds/quake2world$ svn update

If I run q2w from gdb, the screen turns black and nothing happens. After killing the gdb process from a non-X11 terminal, my mouse and keyboard don't work anymore under X11 and my resolution is sth like 640x480 => reboot. Killing the process also means that I can't see what happened in the gdb window, of course. So how do I get more info on what's going wrong?

EDIT: It just came to my mind that I also updated quite a few debian packages so this may also be related to a new gfx driver rather than the latest q2w updates. Question on how to get more info remains though...

Try valgrind?

Looks like a video driver issue. Relevant parts are printed fat:
