OpenGL crashes from igldev32.dll

[Kaiser]

Has anyone who developed openGL ports run across any issues involving igldev32.dll? I've been running into crashes with my gl port played on a Acer laptop (integrated intel graphics chip) and been having trouble debugging it. Are there any tools for troubleshooting this or has anyone else run into this issue before?

These crashes can be reproduced easily but knowing what causes them is still a mystery and all of these crashes are pointing to the dll and not my executable. Not sure anyone would know but I figured I'd ask.

I'd say the best way is to get a backtrace from where it crashes in the DLL for the function you call (unless it's in another thread). If it's in another thread check where it crashed and see if you previously changed any OpenGL thing or anything, back from that point.

Usually any windows DLL won't have debug symbols. I would check Intel's sites for a potential debug enabled DLL or one with symbols available.
