Does this crash occur with Mesa as well? If yes, it might be interesting to step through the Mesa code to see what is going wrong in there.
Otherwise, drivers are never bug free of course. This could be a bug in the Nvidia driver

Hi this fixes http://bugs.winehq.org/show_bug.cgi?id=13599
A +relay trace shows glGetString is crashing inside glGetString. The cause is _not_ a lacking opengl context setup around glGetString. I did some testing and both on windows and wine glGetString just returns NULL if this is the case, but it never crashes inside glGetString:
/* glGetString without opengl context: */ 0009:Call opengl32.glGetString(00001f01) ret=004016bc 0009:Ret opengl32.glGetString() retval=00000000 ret=004016bc
/* Crash from Autocad */
0064:Call opengl32.glGetString(00001f01) ret=1000cd58
0064:trace:seh:raise_exception code=c0000005 flags=0 addr=0x60ec12f6
0064:trace:seh:raise_exception info[0]=00000000
/* and never returns*/
This bug has been reproduced by several other people , so it's also not due to a bad gl-setup on my side. In case you want to try , Autocad trial 2004 can be downloaded from http://www.brothersoft.com/autocad-78351.html. It's the main issue that prevent autocad 2004 up to 2008 from running.
So for now my conclusion is, this is a nasty bug outside wine, and an exception handler is needed to work around the crash. If the patch is rejected i would appreciate some input. Thanks and regards
