Description
The VTM-7.0 decoder (and also current master) crashes when encoding using MaxMTTHierarchyDepth equal to 0.
This is caused by the Adaptive maximal BT-size (AMaxBT) algorithm that update pic_log2_diff_max_bt_min_qt_inter_slice even if max_mtt_hierarchy_depth_inter_slice is equal to 0. (thus pic_log2_diff_max_bt_min_qt_inter_slice is not coded and still use default value of MinQTSize at the decoder).
The crash occurs at picture boundary when MaxBTSize is used.
The issue can be reproduced using the attached config file.
