Subject: Re: OpenCL runtime errors

Hi, since you sad there are some delay, the error might occur in "setup".

So, i put more error treatment in find_best_kpc and  find_best_workgroup 
routines. If you can try this patch and check the results, i will be 
grateful. I expect a "managed" error now.

Thanks.

PS: recently, i haven't read e-mails that are not (directly) sent to me. 
If someone sent a message and need an answer, please just ping me, or 
just wait a week or so.
