ippsc library encode/decode function make my app buffer corrupted

Hi, all,

My application has a memory pool, and any buffer used is allocated from this pool. For EVS codec encoding/decoding, I also get buffer from this pool. But there is buffer corrupted after calling encode/decode function. 

Due to my memory pool is managed by a library and I do not have its source code. I did a test that there is no buffer corrupted if I do not call encode/decode function. So I suspect that ippsc library maybe corrupt user buffer.

Please help me, and if you have similar issue. Thanks.
