295	Mismatch with spec on bS derivation when both sides of the edge have intra_bdpcm_flag equal to 1	chiaming		"According to JVET-N1001-v7, in clause 8.8.3.5, the bS is derived as:
 – If cIdx is equal to 0 and both samples p0 and q0 are in a coding block with intra_bdpcm_flag equal to 1, bS[ xDi ][ yDj ] is set equal to 0.
 – Otherwise, if the sample p0 or q0 is in the coding block of a coding unit coded with intra prediction mode, bS[ xDi ][ yDj ] is set equal to 2.
 – Otherwise, ...
However, in VTM5.0, the bS values for luma and chroma components are all set to 0 when both sides of the edge have intra_bdpcm_flag equal to 1. It is suggested to fix the code from
{{{
if( ( MODE_INTRA == cuP.predMode && cuP.bdpcmMode ) && ( MODE_INTRA == cuQ.predMode && cuQ.bdpcmMode ) )
{
  return 0;
}
}}}
to
{{{
if( ( MODE_INTRA == cuP.predMode && cuP.bdpcmMode ) && ( MODE_INTRA == cuQ.predMode && cuQ.bdpcmMode ) )
{
   return (BsSet(0, COMPONENT_Y) + BsSet(2, COMPONENT_Cb) + BsSet(2, COMPONENT_Cr));
}
