ECM 16.0 encoding crash with AHG7 group4 off

The crash (check failure) may be reproduced by the following command line:

./EncoderAppStatic -c ../cfg/encoder_intra_ecm.cfg -c ../cfg/per-sequence/RaceHorses.cfg -c ../cfg/groupoff/offgroup4.cfg -i ../../../sequences/RaceHorses_416x240_30.yuv -ip 1 -q 37 -f 1

The crash happens at the first frame. The encoding log is as below. The check failure happens under the macro JVET_AK0059_MDIP.
