GLSL function overloading


I’m running on windows XP and I’m having an issue with the NVidia drivers 185.85 on an 8800 GTX. It appears that my glsl code with function overloading that used to work, is now complaining. If I remove the function overloading, the code runs fine. Has anyone else here noticed this issue?

I’m wondering if it’s a driver bug or if it’s something I’m doing incorrectly.

Thanks for any input.
