opencl visual profiler throwing error

hello everyone,

The opencl Visual profiler is giving error. when i try to profile my code it throws an error:

=== Start profiling for session ‘Session1’ ===
Start program ‘/home/gauri/NVIDIA_GPU_Computing_SDK/noise_filter/Second_OpenCL. cpp’ run #1
Program run #1 failed, exit code: 255
Error in program execution.

Can anyone please tell me what kind of error this is and what may be causing it. The library path are set. So i doubt if that is a problem. The code is running fine without the profiler.
