ippiMalloc_8u_C1 returning wrong dstStep?

Im using ->

ippCore 2019.0.0 Gold (r59881)

On a mac

IppiSize dstSize = { 480, 270 };

Ipp8u* pDst = ippiMalloc_8u_C1(dstSize.width, dstSize.height, &dstStep);

ippiMalloc_8u_C1 returns dstStep=512 resulting in a 32 pixel black border on the right side of the picture.

However 480 is integer dividable by 32 (if that is a requirement to be 32 bytes aligned in the line by line stepping) and forcing dstStep to 480 works for all following processes I use and the black border is gone.

I use the example code ->

Am I doing something wrong or is it a bug?

Thanks for helping.
