Description (last modified by XiangLi)

When running debug version of encoder (compiled by VC2010) under Cygwin as follows, segmentation fault was observed.

./TAppEncoder.exe -c c:/cfg/encoder_intra_jvet10.cfg -c c:/cfg/per-sequence/BasketballD.cfg -f 1 -ip 1 -q 22 --SEIDecodedPictureHash=1

The encoder output was as follows

POC 0 TId: 0 ( I-SLICE, nQP 22 QP 22 ) 98992 bits [Y 43.1048 dB U 44.6860 dB V 44.8941 dB] [ET 382 ] [L0 ] [L1 ] [MD5:e574ec244ffcd7444b4f649c576f5d9e,147b8b2dd665f75652082165c0b4775a,a5eca27490b36b9adf0bbaf4fb182bfb]
Segmentation fault.

The segmentation fault was only observed for debug version. Release version looks OK.

The bug was related to the memory allocation in SDT. The fix (r150) has no impact on coding performance under CTC.
