IPP 9.0.4 DFT problem?

Hi All,

I used ippiDFT functions from "Intel Parallel Studio XE 2016" on platform Windows 7 x64. For ours purpose we would like to use DFT functions with multi-threaded version. This functions works correctly with different number of threads. So far  there is no problem. The problem is, when we compile our application with openmp flag, DFT starts produces garbage when threads number used to calculation is different than 1. I prepared test source codes in attachments. But before that, let me write more details.

1) Scenario 1 - without "openmp" compilation flag
It doesn't matter if I use static or dynamic linking, prepared codes works correctly, and produces correct results for all configuration threads. In my case it is 1...8 Threads. That's fine.

2) Scenario 2 - with "openmp" compilation flag.
Right now linking method have matter. If we compile with dynamic linking, still everything looks correct, and results are correct for each threads configuration. But when I use static linking, DFT produces good results only for one thread. Other thread configuration produces garbage, without reporting any error from function call. This problem occur even function calls are not using omp statements.

Platform spec:
- CPU: i7- 4790K
- Windows 7 x64
- Intel Parallel Studio XE 2016, IPP version 9.0.4, build date: Aug 4 2016.
- Visual Studio 2015 Community edition
- Linking method in both scenarios is multi-threaded

Sample code is in attachment.
Is this bug? or there is any reasonable explanation?

Thank you in advance.
