 Summary of the bug:
 FFmpeg causes OOM issue when trying to trim and concat a video sequence
 from a single source with long filter_complex_script (194 audio and 194
 video tracks)
 How to reproduce:
 {{{
 % ffmpeg -i video.mp4 -filter_complex_script fil2.txt -map "[v]" -map
 "[a]" output.mp4
 ffmpeg version 6.1.1
 }}}

 This issue occurs only in FFmpeg 6.1.1, I tested on a VM with Ubuntu
 Server 22.04 with FFmpeg version 4.4.2 and the command executes
 successfully without OOM
