This patch should fix it.  Posted for review.

The proposed patch does not work for me, it still returns true.
Comment 3 Brian Paul 2013-02-26 15:14:40 UTC
Hmm, I retested here and it works.  Are you sure everything was rebuilt properly?  The get_hash.h file gets regenerated from the get_hash_params.py file (which is what we're patching).  Could you try rm'ing get_hash.h and rebuilding?
Comment 4 Blaž Hrastnik 2013-02-26 15:18:15 UTC
Hmm, I probably rebuilt it incorrectly, I used ArchLinux's PKGBUILD file to auto build it into a package (and apply the patch beforehand), the build system probably splits these packages differently (I ended up with mesa as well as several driver packages). I'll try it again, and if it doesn't work, I'll manually build it.
Comment 5 Blaž Hrastnik 2013-02-26 15:37:42 UTC
Ah yes, apparently it was in the "ati-dri" package that arch built. Works properly now, thanks! By the way, I have some more unresolved bugs (Regarding OpenGL 1.x-2.1) on a opengl ruby binding library (https://github.com/archSeer/opengl), so be on a lookout, I'll report probably 2-3 more in the next few days.
Comment 6 Blaž Hrastnik 2013-03-02 14:49:26 UTC
Brian, has the patch been merged yet?
Comment 7 Brian Paul 2013-03-04 15:45:02 UTC
Thanks for the reminder.  I just pushed it.
