Hi,
we noticed that the new Intel OpenCL CPU only runtime series 7.* crashes in its OclCpuBackEnd64.dll during the clBuildProgram() method when a rather long source code is passed. The very same piece of code is working properly under the previous versions of the Intel OpenCL CPU only runtime (version 6.* and earlier), as well as under the NVidia, AMD, and Intel GPU runtime.
By cutting a few dozen lines of code, the clBuildProgram() works.
We are facing this problem under all the 7.* CPU only versions we can test in our firm:
- 7.0.* (the one available as Experimental through the Intel OpenCL SDK)
- 7.2.* (as the CPU only runtime available with the HD Graphics driver)
- 7.5.* (as the CPU only runtime availabe with another Intel GPU)

Thanks for this report. The team will be glad to investigate this bug, but to do so we will need kernel source showing this problem as a reproducer. If there are any concerns with posting to a public forum you can use the "send author a message" link by my name to send a private message.

Hi Jeffrey,
thanks for your answer. I've no problem in privately sending you the code snippet, but I can't find the "send message" option you mentioned. I can drop you an email if you provide me your address.

Alternately, if this does not work for any reason, my email is jeffrey.mcallister@intel.com.
Nada, I only have "quote" and the post number. Maybe Chrome is not friendly enough. Will send you an email right now, thanks.
