WINEDEBUG trace, including R600 shaders

Hardware tested: Linux x64, both HD4890 and HD6450

World of Warcraft (OpenGL mode) has been crashing ever since it upgraded itself
to 6.2. I had assumed that it was a bug in the WoW client, until I noticed that
WoW did not crash on a machine running with the NVIDIA binary blob.

I have executed WoW using the following command:

$ R600_DEBUG=fs,vs,gs,ps,cs WINEDEBUG=+opengl,+wgl,seh ./Wow-64.exe

And it appears that WoW is throwing an exception in a glLoadMatrix() operation:

trace:opengl:glCallList (1)

trace:seh:raise_exception code=c0000005 flags=0 addr=(nil) ip=0 tid=0027

I don't know how to debug this any further; the more flags I add to WINEDEBUG,
the less likely WoW is to do *anything* (i.e. "run at all"). Raising this as a
means of requesting more ideas.</pre>
