[Wine] Segfault in SolidWorks with recent nvidia cards and drivers

[denisb]

Hello, 

I upgraded my config to  and i7.2600/quadro600 setup running ubuntu natty 64bits with 3.1-rc kernel (needed for correct asus P8P67 EFI support) and 280 or 285 Nividia proprietary drivers, and I'm experiencing systematic segfaults when running solidworks 32bits ( version 2010 or 2011 ) : the part is displayed in 3D, and then the application is closed immediatly. There are no traces in console, even with x11drv debugs, except this line in kern.log

bureau kernel: [40526.805397] sldworks.exe[10445]: segfault at cfc0000 ip 000000007e9d61cb sp 000000000033ef80 error 4 in comctl32.dll.so[7e9b1000+b8000]

or

bureau kernel: [22199.624096] sldworks.exe[5631]: segfault at c4e0014 ip 000000004ec5f75b sp 000000000032e964 error 4 in gdiplus.dll[4ec52000+185000]

with native gdiplus 

The same wineprefix works perfectly on my old GF6800, and partially on really old i855 notebook. So I suspect a bug in recent nvidia drivers. Unfortunately, older ones can't be compiled with 3.x kernels. 
I tried to downgrade wine too, without success

I tried some games ( Sims3, Spore...) and they work perfectly, so the problem seems to be specific to Solidworks or some other OpenGL Apps

Does anybody experienced the same problem ? Is there a way to trace opengl calls ?

Thanks
