Hi,

we have a .NET application has memory leak, the stack shows it comes from the invoke to ippsVLCEncodeOne method, but we didn't call it directly.
in what kind of scenario it will be called?

Hi,

our c++/cli project call IPP from the DLL, dynamic link.

currently we suspect the problem is come from the compress/decompress code, it's from the IPP demo,

EncodeRLE
ForwardBWT
ForwardMTF
EncodeHuffman
