Arch Linux

Description: Applications like glxgears and glxinfo segfault after the mesa/libgl upgrade to 7.4.4. I can't confirm this on anything other than savage hardware.

Additional info:

Direct rendering still seems to work. I get about the same framerate in quake3/tremulous as I did before.. I'd be more than willing to provide any additional information on request. Here's the most relevant bits regarding this bug:

Steps to reproduce:
1. Have the pleasure of owning S3 hardware
2. upgrade to Mesa 7.4.4 from 7.4.2
3. enjoy crashing mesa utils!
