1216	Out of bounds array access (8.5.6.6.3)	fbossen		"It seems that input values refIdxL0 and refIdxL1 may be equal to -1 (for example, see assignments in (456), (519), (649)). In such case, they should not be used to index arrays LumaWeightLX, luma_offset_lX, ChromaWeightLX, and ChromaOffsetLX.

Assignments such as
w0 = LumaWeightL0[ refIdxL0 ]
could be changed to
w0 = ( refIdxL0 >= 0 ) ?  LumaWeightL0[ refIdxL0 ] : 0

or the assignment could be conditioned on predFlagL0:
When predFlagL0 is 1, the variables o0 and w0 are derived as follows:
  w0 = ( cIdx == 0 ) ? LumaWeightL0[ refIdxL0 ] : ChromaWeightL0[ refIdxL0 ][ cIdx − 1 ]
  o0 =  ( ( cIdx == 0 ) ? luma_offset_l0[ refIdxL0 ]  : ChromaOffsetL0[ refIdxL0 ][ cIdx − 1 ] ) <<  ( bitDepth − 8 )
