Subtitle problem in new ffmpeg version transcoding crashes with sume subtitles

[Wkuf]

Summary of the bug: I used ffmpeg version N-99878-g406879f to code my videos since many years without problems. After recompiling ffmpeg version N-112494-g393d1ee541 the option -scodec dvdsub crashes videos with dvb_subtitle in a ts file. If I transcode the same video with the old version everything is fine.
How to reproduce:

% ffmpeg -y -itsoffset 0 -threads 4 -i /mnt/00001_Neo_test_dd_abspielbar.ts -ss 00:00:02 -to 00:00:14 -filter_complex "[0]yadif=0:-1:0[deint]" -map "[deint]" -map 0:a -map 0:s:0 -codec:v libx264 -preset veryslow -crf 23 -c:a libfdk_aac -b:a 128k -scodec dvdsub /mnt/00001_Neo_test_dd_abspielbar_ffmpeg_new.mkv

I added two log files
fmpeg-20231103-193114_new.log is the result of the crash with version N-112494-g393d1ee541

ffmpeg-20231103-193512_old.log is the result of the old version that generates perfect output files including the correct subtitle

I uploaded 00001_Neo_test_dd_abspielbar.ts to the uploadserver

Thank you. Great that you checked this.

The coding is now running through but the subtitles are not in Sync and are very much shifted. It is not happening for the small example that I uploaded but for a larger file. VLC does not recognice the length correctly of the coded file.
