I couldn’t find an official “submit bug” spot in the dev zone so I’m posting this here:
Driver v335.23 on Win8.1 Pro x64 with Geforce GTX 680
Code is running D3D 11.0 feature level 11 in an x64 debug application with the debug device. The crash also occurs in release mode.
I get a crash on a thread in the driver in nvwgf2umx.dll:

The flags for D3DCompile() are:
D3DCOMPILE_ENABLE_STRICTNESS | D3DCOMPILE_PREFER_FLOW_CONTROL | D3DCOMPILE_DEBUG | D3DCOMPILE_SKIP_OPTIMIZATION
Finally what’s even crazier is that this crash seems to be caused by a simple multiplication in my shader. Specifically a shader that works fine:
float3 light;
float ndotl;
swith(lightType)
{
case X:
{
light = blah;
ndotl = dot(lightDir, normal);
light *= ndotl;
break;
}
}
Crashes:
float3 light;
float ndotl;
swith(lightType)
{
case X:
{
light = blah;
ndotl = dot(lightDir, normal);
break;
}
}
light *= ndotl;
I can provide a sample application and the actual shaders upon request. Thanks!
