Hi All,

We've got an error with our GLSL shader running with specific card only. The log is:

> OpenGL Vendor: NVIDIA Corporation
> OpenGL Renderer: NVIDIA GeForce 7300 GT OpenGL Engine
> OpenGL Version: 2.1 NVIDIA-1.6.36
>
> [OK] OpenGL Shading Language is available!

> maxLights = 8, maxTextures = 8
>
> (0) : fatal error C9999: Unexpected branch instruction
> Cg compiler terminated due to fatal errorAbort trap

Any advice (what to check and where to find) is highly appreciated.

Thanks

And the shader code is? 7300 is a pretty old card with low specs. It could be anything.

Start by looking at your shader. See if you can improve it.

an open source GLU replacement library. Much more modern than GLU.
float matrix[16], inverse_matrix[16];
glhLoadIdentityf2(matrix);
glhTranslatef2(matrix, 0.0, 0.0, 5.0);
glhRotateAboutXf2(matrix, angleInRadians);
glhScalef2(matrix, 1.0, 1.0, -1.0);
glhQuickInvertMatrixf2(matrix, inverse_matrix);
glUniformMatrix4fv(uniformLocation1, 1, FALSE, matrix);
glUniformMatrix4fv(uniformLocation2, 1, FALSE, inverse_matrix);
