Backtrace

The game The Witcher (running in Wine) crashes shortly after start:

u_vbuf_mgr_draw_begin+0x198(mgrb=0x7c5937c0, info=0x1c6ec5c, buffers_updated="À`¬d|", uploader_flushed="") [/home/sa/Programming/gfx/mesa/mesa/src/gallium/auxiliary/util/u_vbuf_mgr.c:549] in r300_dri.so (0x01c6e9f4)

This does not happen in 7.10. Bisecting leads to this commit:

I'm attaching a backtrace, but I'm not sure how helpful it is, as getting it from Wine was quite tricky.
Comment 1 Marek Olšák 2011-06-08 16:44:43 UTC 
Is this still an issue with current Mesa git? If yes, could you please make a GL trace using apitrace? (basic info about tracing: https://bugs.freedesktop.org/show_bug.cgi?id=36745#c15 )
Comment 2 Sven Arvidsson 2011-06-11 14:52:35 UTC 
Doesn't seem to be an issue with current git master.
