--- Comment #57 from H. Verbeet hverbeet@gmail.com 2008-06-14 04:38:10 --- It's probably line 2536 @ dlls/wined3d/state.c triggering the crash then: GL_EXTCALL(glTexBumpParameterfvATI(GL_BUMP_ROT_MATRIX_ATI, (float *) mat));
I don't have an ATI card with fglrx myself, but it would be interesting to know if this is indeed causing the crash, and if someone can reproduce it in a small standalone GL application (using eg. glut). Also, if this is indeed 64-bit specific, it might be significant if the application itself is 32-bit (ie, compiled with gcc -m32, like Wine) or 64-bit.
@Chris Ahrendt & other people claiming they run into this bug on 32-bit systems: could you confirm the second entry in the backtrace is a call to ActivateContext? If it isn't, this is a different bug.
