ffmpeg crashes with double free or corruption when stream copying timecode track

[Andrew Hunter]

ffmpeg crashes with double free or corruption when encode is interupted with 'q'.

I have also attached a sample of the file that crashes.

$ ffmpeg -i side_effects_graded.mov -vcodec prores -profile:v 3 -vf crop=2048:872:0:140 -s 2048x872 -dcodec copy -map 0:0 -map 0:1 -threads 4 /media/Media/Projects/Side\ Effects/side_effects_graded_crop.mov
