System Information
Windows 10, 2x AMD Radeon R) 270X

Blender Version
Broken: 2.76 (latest patch) and 2.77 (release)
Worked: none

Short description of error
I tried to open the blend and blender just crashes with an EXCEPTION_ACCESS_VIOLATION.
Things seen before this happened: I got an FPE exception earlier with that blend, and the animation updates were asynchronous (i.e., of the three animated objects, sometimes one of them - not a specific one - didn't update when going one frame forward; a few times it even updated in the reverse direction); also, most of the time at least one of the fire generators didn't produce fire, but I thought this could be because of my lack of experience with smoke simulation.

Exact steps for others to reproduce the error
Try to open the file.

Tested, the file loads fine here, (64bit Arch-Linux, official 2.76 and 2.77).

Although it runs here on Linux too (openSuSE Leap 42.1 x64), it is pretty unstable (i.e., fire from moving objects isn't generated for some frames until I rewind and step forward over that frame again, and sometimes object positions aren't updated when changing the current frame by single-stepping). Now it crashed in 'FLUID_3D::advectFieldSemiLagrange(float, float const*, float const*, float const*, float*, float*, BasicVector::Vector3Dim, int, int)', coming through 'smoke_turbulence_step' (it's the official release blender-2.76b-linux-glibc211-x86_64.tar.bz2, md5 e588925227f699cc93b62bc00eb58916).

Is the file still available? It gives 404 when i'm trying to download it. if it's small enough please upload directly to the developer.blender.org.

Should be available now again.

Can not reproduce the issue on Linux and Windows 7.

Please download opengl32.dll from ftp://ftp.blender.org/sergey/softwaregl/ and put it next to blender.exe. This will switch blender to software opengl which is slower but free from vendor-specific glitches. This would allow us to understand if it's related to opengl or not.

Runs fine with that DLL, and my drivers are up-to-date. I could try to build blender myself to debug it.

Steffen Ohrendorf commented

Peeked around a bit in your FTP and found the debug build; starts fine without that blend, but still crashes. The problem seems to be a NULL-pointer dereference in my drivers (to be exact in atig6txx.dll), and the line of code in blender itself is a call to ChoosePixelFormat in choose_pixel_format_legacy.

Here's the complete backtrace, excluding useless in-driver stack frames:

So that’s OpenGL driver bug again, sorry but we can’t do much about it (especially if we cannot reproduce it), you can hope and wait for a newer driver to fix it, and/or check the following points:

Try to tweak OGL settings in UserPreferences, System tab.
Try to tweak your GPU driver settings (e.g. try different values between 'performance' and 'quality' if you have such slider, etc.).
