HM3.2 Decoder crashing for QP=1 RA LC

Description

For WVGA50_PartyScene for QP=1 for RA-LC configuration, decoder is crashing at different points for debug and release versions. For debug versions, 3 frames are decoded perfectly before failing at an assert statement. To replicate the crash, it is enough to encode just 9 frames and try to decode the bit-stream.
