We are using IPP version 220.127.116.11 on 4th generation (Haswell) Core i7 processor under INtime (5) operating system.
We are using static linkage (#include <ipp_h9.h> before #include <ipp.h>).
A call to ippsFFTInitAlloc_C_32fc causes an invalid opcode exception. This occurs inside h9_ippsFFTGetSize_C_32fc function when trying to execute the les esp,edx instruction.
Note: When configuring IPP for AVX rather than AVX2 (using ipp_g9.h instead of ipp_h9.h) - everything works correctly. It so happens that g9_ippsFFTGetSize_C_32fc does not compries that les instruction.
We verified that our processor supports AVX2 (ran the piece of code suggested by Intel for checking this).
