Thank you for the project file. I can confirm the crash. With GDB running no crash happen. It seems to be a race condition.
Thanks for your detailled report, this was an interesting bug. MLT's keyframes are currently quite limited and the smooth interpolation uses a Catmull interpolation which sometimes produces some unexpected curve path. Some work is being done on it: https://github.com/mltframework/mlt/pull/957 So in fact the Transform effect keyframes were requesting a 0x0 rectangle, which crashed the Rotoscoping effect. I now fixed these issues in MLT git and it will be included in our 23.08.2 binaries.
