backtrace

When running Smoothed Particle Hydrodynamics from Chrome experiments there is a
assert failure in state_tracker/st_glsl_to_tgsi.cpp:3082:simplify_cmp:
Assertion `inst->dst.index < 4096' failed.

This is with i915g driver. I did also tested llvmpipe, however webgl is
disabled with it. r300g fails to initialize the shaders (but doesn't crash).
