#1371 closed defect (fixed)

reserved_zero_43bits[32..42] written using 12 bits instead of 11 bits

Description

Revision 4252 of HM-dev introduced a serious bug that can be fixed as follows.

In TEncCavlc::codeProfileTier(), the following line

    WRITE_CODE(0x000  , 12, PTL_TRACE_TEXT("reserved_zero_43bits[32..42]"    ));

should be changed to

    WRITE_CODE(0x000  , 11, PTL_TRACE_TEXT("reserved_zero_43bits[32..42]"    ));

This is a serious issue and generates bitstreams that cause the HM decoder to crash.
