Backtrace

Since commit e78a01d5e6f77e075fe667a0f0ccb10d89c0dd58 3DMark2001 crashes in the
Nature test when it is run in Wine with the ARB shader backend on r300g.

The 3DMark2001 download can be found here:
http://www.futuremark.com/benchmarks/legacy

I used Wine 1.7.22 for testing, but I am certain that the bug can be reproduced
with newer Wine releases because the ARB shader code hasn't been changed in a
white. My GPU is a Radeon X1600.

To reproduce the bug you have to enable the ARB shader backend by starting
Wine's regedit and setting HKEY_CURRENT_USER/Software/Wine/Direct3D/UseGLSL to
disabled. Create the Direct3D key and UseGLSL string value if needed.

I do not see the crash on r600g (Tested with 9a071e33, Radeon HD 5770).

A backtrace is attached. The backtrace was generated with Mesa 1c4f141a.
