I'm using Very Sleepy CS to do profiling, if that matters.
IPP(Intel's Integrated Performance Primitives) are used in my project, basically for a single call:
ippsExp_64fc_A26(reinterpret_cast<Ipp64fc*>(delta_vector.data()), reinterpret_cast<Ipp64fc*>(delta_vector_out.data()), delta_vector.size());
It is a bug indeed. Visual Studio's profiler shows no sign of the mentioned function.
