1063	The latest VTM decoder crashes when multi-layer coding is tested	ZhipinDeng		"The latest VTM decoder crashes when BL single subpic and EL multiple subpic in multi-layer coding. 

The crash is triggered by the following check introduced by JVET_R0276_REORDERED_SUBPICS:

CHECK( currentSubPicIdx >= pcSlice->getRefPic( RefPicList( refPicList ), refIdx )->subPicIDs.size(), ""Number of sub-pictures in a reference picture is less then the current slice sub-picture index"" );

I noted that there is another check introduced by JVET_R0276_REORDERED_SUBPICS: 

CHECK( pcSlice->getRefPic( RefPicList( refPicList ), refIdx )->subPicIDs[currentSubPicIdx] != pcSlice->getSliceSubPicId(), ""A picture with different sub-picture ID of the collocated sub-picture cannot be used as an active reference picture"" ); 

I understand the second check, but don't understand how the first check relates to the JVET-R0276 adoption."	defect	closed	minor	VTM-9.0	VTM		fixed		ksuehring XiangLi fbossen jvet@…
