I get the same bug running glxinfo and glxinfo64.
I hope this helps reproducing the bug.

Actually this unlikely to be a duplicate of that bug. This bug might be
resolved by

http://cgit.freedesktop.org/mesa/mesa/commit/?id=c092c46b27c6f6a6674e8d67fb3afdb684811819

But I'm not 100% sure... mind trying it out?

You may be 100% sure now:I tried your patch and it fixes my problem, both the
