Description

Upgrading from Mesa8.x to any version of 9.x (or 10.x-devel) results in a segmentation fault in dri/gallium. Following all details:

OS: Fedora 18 CPU: Intel Atom N450 (integrated GMA 3150 GPU)

    Run 'gmake' to build Mesa

...

Run egl example (that runs under 8.x, but not under any version of 9.x or 10.x-devel) on console (with no X at all!!!)
