Intel IPP memory alignment required or optional?

Hi all,

I am using Intel IPP in a project and it works great most of the time, but I still have few unexpected memory access violations.

Could you confirm that memory alignment is optional in every ipp function? I often work with ROI in images and so ROI buffers are no necessary aligned.

Is there any known bug with ippiCopy, ippiScale or ippiSwapColor? In my program I removed all the code except image format conversion based on the three listed functions and it occasionnaly crash.

For information, my main app is C# and WPF and I have a C++ DLL which contains calls to IPP function. I only use SSE2 optimized dlls.

I checked and double-checked everything. This is really strange...

Also, does any one know if we could use IPP with Visual Studio 2017? At the moment it is not listed at the install stage and I did not found any information on update for VS2017.

Thank you,
David
