Created attachment 53196 [details]
output with INTEL_DEBUG=all

Hi there,

I noticed that with recent mesa FEAR crashes with an assertion. With recent I mean that the issues seems to be present since some revisions. I went back a couple of weeks and also tried regression testing, but a lot of revs are broken (with different issues) so I gave up.

Anyway, the triggered assertion is:
o.exe: brw_vs_emit.c:1406: get_dst: Assertion `c->regs[dst.File][dst.Index].nr != 0' failed.

I attached the full output (with INTEL_DEBUG=all), compressed with XZ.

Also searched the bugzilla and _maybe_ this one is related to bug #34201. However I'm positive that this was working at the beginning of 2011. Dunno if some changes to wine are triggering this issue.

Greets,
Tobias

P.S.: System specs:
Intel Corporation Arrandale Integrated Graphics Controller
vanilla-kernel 3.0.6

Seems to be fixed with recent mesa git master.
