program hangs on linking IPP for runtime dynamic library

Hi,

I'm linking the non-threaded version of IPP library statically for building runtime dynamic library. I am using GCC compiler on Ubuntu 18.04.

The code hangs sometimes (once in a 5 times approx.) on calling the following IPP call

ippiOr_8u_C1R(src1,8,src2,8,dst,8,DstROI);

Is this a linking issue? As the program runs fine if the library is used to build a executable instead of the library. Please help.

The following is the system configuration

ippCore 2020.0.1 (r0x35c5ec66)
