Possible bug in ippsDecodeLZ4_8u

Hi.  I think there should be something that is not working correctly in the ippsDecodeLZ4_8u() function.  For example, the next code work flawlessly:

#ifdef HAVE_IPP
  int outlen;
  int inlen = (int)compressed_length;
  IppStatus status;
  //status = ippsDecodeLZ4_8u((const Ipp8u*)input, inlen, (Ipp8u*)output, &outlen);
  status = ippsDecodeLZ4Dict_8u((const Ipp8u*)input, &inlen, (Ipp8u*)output, 0, &outlen, NULL, 1 << 16);
  cbytes = (status == ippStsNoErr) ? inlen : -inlen;
#else
  cbytes = LZ4_decompress_fast(input, output, (int)maxout);
#endif

However, if I comment out the ippsDecodeLZ4Dict_8u() line and uncomment the one with ippsDecodeLZ4_8u() the code only works in debug mode (-O0 -g), not in Release mode (-O3 -g).  I am using IPP 2019.1.144 on a Mac with OSX 10.4.2 and clang 1000.11.45.5 (Apple LLVM version 10.0.0).

Any hint will be appreciated.
