Bug 2593

Some further testing shows this does not really cause a gpu lockup. It actually
segfaults, but behind a LOCK_HARDWARE, and is unable to recover from that.
This appears to be the same bug as #2516, since the crash happens within a
rasterization fallback (GL_SELECT render mode). Backtrace looks the same too
(using the same method to get a backtrace locally as there).

Program received signal SIGSEGV, Segmentation fault.

This has nothing to-do with gl-117.   
 
TNL build vertices bug. 
 
See my post about 'texdown - 'b'-button' in DRI-Devel.

Maybe you or I should open a bug report, here.

Indeed.

This happens only with rasterization fallbacks. Thus I believe #2516 should
track this well enough.
