Hi Robert,

  I have tested on both Intel and Nvidia machines.  The solution works without any issue.  Thanks.

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;


   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.
