AMR Encoder Getting stuck in e9_ownSearchOptimalPulsePos_M122_GSMAMR_16s_optSSE

Our software which has Intel IPP library randomly goes to hung state when AMR packets are being encoded.

Since it was hanged, our software watchdog was not creating any gdb cores and the it was randomly getting restarted.

We had added a special condition in the watchdog for this kind of scenario to dump gdb core.

While analyzing the gdb core, we found that it got stuck in below code.

Hello,

IPP speech codecs were deprecated stopped to support in 2015 year: https://software.intel.com/en-us/articles/the-alternatives-for-intel-ipp-legacy-domains-and-functions

Unfortunately we do not support this algorithms any more.
