Default glxinfo crashes xserver when __GL_SYNC_TO_VBLANK=1 is set

Hi,

I found that with 171.06, running glxinfo with __GL_SYNC_TO_VBLANK=1 will cause the
X server to crash. The crash leaves the following on the console:

Backtrace:
0: X(xf86SigHandler+0x6a) [0x47abba]
1: /lib64/libc.so.6 [0x2b5693ee08c0]
2: /opt/XOrg/lib64/X11/modules/drivers//nvidia_drv.so [0x2b56967123e0]

Fatal server error:
Caught signal 11. Server aborting.

This is on a multilib x86_64 system, running xorg-server-1.4

Note that if I unset __GL_SYNC_TO_VBLANK first, glxinfo does not crash.

I'm attaching my nvidia-bug-report.log file.

I still see this with 173.x and 177.x using glxinfo and nvidia-settings. I just set the variable to 0 in my scripts before running nvidia-settings to get various info about the card. nvidia-bug-report.sh took X with it earlier tonight, maybe that script could (un)set it also?
