IPP calling unsupported CPU instruction

Hi,

I am working on a software for image processing that uses IPP-9.0.0 and got mini-crashdumps from user.

It appears, that function

ippiResizeNearestInit_8u

on user machine is trying to perform CPU instruction

vcvtusi2sd

which, according to various sources, belongs to AVX512F instruction set, yielding exception 0xC000001D: Illegal Instruction.

DxDiag on user machine shows that Intel(R) Xeon(R) CPU E5-1650 v2 @ 3.50GHz (12 CPUs) is installed, which only supports AVX instructions. As a result, IPP should have chosen the implementation without instruction metioned above, but it did not.

What could have caused such behaviour on IPP side and can something be done to workaround that problem?

Thank you!

Hi Alex,

Please try one the latest versions - at least IPP 2019. IPP 9.0 is very old version and has a number of known bugs that have been already fixed in the next versions,
