os: 32 bit
Bug detailed description:
We run 3DMarkMobileES2.0 on T410 32bit system with the newest code on mesa master branch, it can't run with "Segmentation fault". I find it can run without segmentation fault before glsl2 branch merge to master branch. And with the merge point of glsl2 to master or on glsl2 branch, it will has such issue.
There is a message in dmesg: 3DMarkMobileES2: segfault at 4 ip 080691be sp bfb316c0 error 4 in 3DMarkMobileES20[8048000+67000]
The backtrace is as following.

run the 3DMarkMobileES2.0 with newest code in mesa master or glsl2 branch.
I can't reproduce this, sorry. I tried building 3DMarkMobileES2.0 on my 64-bit Linux system and hit all kinds of build failures due to #include picking up 3DMark's "string.h" and "math.h" rather than the system headers. After patching 17 different files I was able to get it to build, but it crashes at application startup, well before any real work is done.
So I'm not sure how to proceed.
I don't believe this bug should delay the Q4 release. ES is still a somewhat new and thus experimental feature (though working more and more each time!), and I don't think this is a regression from prior releases. We also still haven't tracked it to a specific issue in our driver.
It still warrants looking into, but I don't think it's a top-priority bug.
agree this doesn't block Q4 release.
but note this is regression as the original description mentions this worked before glsl2 merge.
It seems to run with Mesa master, which has Chad's fixes for dealing with the "precision" qualifier.
Last I checked (some time ago) 3DMarkMobileES2.0 runs without crashing. Closing this report. There are likely other 3DMarkMobileES2.0 issues, but they can be opened as new reports.

With the newest code in master branch and kernel in drm-intel-next, the 3DMarkMobileES2.0 was successfully begin to test instead of crashing. Tested with:
