On my search I came across suggestion of lack of support on OSX and GLES. I don't know how correct/up to date this is. Could you try replacing the if (isnan(num_iterations)) num_iterations = 2.0; With: if (num_iterations!=num_iterations) num_iterations = 2.0; I would try myself by my system that had the latest NVIdia drivers that show this bug has died due to a disk failure. I will need to buy and new disk and get everything back installed on it. This isn't something I can tackle today though.
