I checked the code and found that there is no actual access to fields that don't exist. Changing `acMvAffine4Para[2][2]` to `acMvAffine4Para[2][3]` is a functioning workaround. Note: I could not reproduce the issue with gcc7 on macOS or Scientific Linux." defect closed minor VTM-5.1 VTM VTM-5.0 fixed ksuehring XiangLi fbossen jvet@…
