2b5de09b3ea8754fb004d4f216bca29303f99490 is the first bad commit commit 2b5de09b3ea8754fb004d4f216bca29303f99490 Author: Brian Paul <brianp@vmware.com> Date: Tue Mar 23 17:55:41 2010 -0600 swrast: improve depth texture mipmap selection We still don't do proper min/mag filtering but this is better than just sampling the base mipmap level all the time. Fixes piglit depth-level-clamp test. Fixes fd.o bug 27256. :040000 040000 df45cad5ad0657b356c7472c5eea1a1e9052a303 9a4258e852c08e4d8934765d29c4cc7c9a6f2a82 M src bisect run success
Looks like the Sep 30 change to the test itself exposed this bug. Fixed in Mesa/master with commit fb5e6f88fc426e53af26e98d1c336222a8952cc5. I'll cherry-pick this to the 7.9 branch after you verify the fix, Vinson.
mesa: 2cf3199ee3b0014bc426bc3163dfa279c00eabb3 (master) Verified that the crash is fixed.
OK, cherry-picked to 7.9 now too.
mesa: 34c518be52958c9facd294955a81286293a6ed0b (7.9) Verified fixed on 7.9 branch.
