offline/online opencl compilation difference

Dear Community Members!

I have a program, which makes some calculations with the help of the opencl kernel, which runs on the cpu. I also make these calculations  without opencl and check for errors.

 

The problem is that I get errors from time to time, when I use online compilation of opencl kernel. I don't get errors, when I use offline compilation. 

Could anyone, please, help me and explain, why it happens?

You can find files here:

ioc64 -cmd=build -input=prog1.cl -device=cpu -ir=prog1.bc

 for offline comilation.

Vendor: Intel(R) Corporation
Version: OpenCL 1.2 LINUX

CPU: Intel(R) Xeon(R) CPU E5-2609 v2 @ 2.50GHz
