CUDA 6.5, OpenCL errors


I have updated my CUDA version to 6.5. Since the update, my OpenCL program has stopped working (clBuildProgram crashes, withouth launching any exception, indicating nvopencl.dll as the module with the error).

I am pretty sure it is some kind of library or driver related problem (or maybe an installation problem?), because if I run the OpenCL Volume Rendering example (found here: the program does not work propperly (My app is similar to this example), but the corresponding demo using CUDA (launched from the CUDA Samples) works just fine.

Do you know about some bug related to this, or have experienced something similar?

The same problem appears using several Nvidia GPUs.

Thank you.
