1175	Longterm Reference related uninitialized variables	takamura		"Encoder bug since VTM-5.2 up to current.
When long-term reference frame is used, delta_poc_msb_present_flag and delta_poc_msb_cycle_lt are not initialized, hence they are sometimes included, sometimes not included in the bitstream.
Need to add two lines in ReferencePictureList constructor.

ReferencePictureList::ReferencePictureList( const bool interLayerPicPresentFlag )
  : m_numberOfShorttermPictures(0)
  , m_numberOfLongtermPictures(0)
  , m_numberOfActivePictures(MAX_INT)
  , m_ltrp_in_slice_header_flag(0)
  , m_interLayerPresentFlag( interLayerPicPresentFlag )
  , m_numberOfInterLayerPictures( 0 )
{
  ::memset(m_isLongtermRefPic, 0, sizeof(m_isLongtermRefPic));
  ::memset(m_refPicIdentifier, 0, sizeof(m_refPicIdentifier));
  ::memset(m_POC, 0, sizeof(m_POC));
  ::memset( m_isInterLayerRefPic, 0, sizeof( m_isInterLayerRefPic ) );
  ::memset( m_interLayerRefPicIdx, 0, sizeof( m_interLayerRefPicIdx ) );
+  ::memset( m_deltaPOCMSBCycleLT, 0, sizeof(m_deltaPOCMSBCycleLT) );
+  ::memset( m_deltaPocMSBPresentFlag, 0, sizeof(m_deltaPocMSBPresentFlag) );
}
