 Hello,
 The following command used to work in FFMpeg 4.4, but in FFmpeg 5.0 causes
 a segmentation fault. If I remove the audio “join” filter the segmentation
 fault does not occur.
 See attached file for debug output and gdb output are below. I encounter
 this segmentation fault on Ubuntu 20.04 as well.

 ./ffmpeg -v 9 -loglevel 99 -i
 /tmp/HD5_720_DVCPROHD_Horizontal_Progressive_NoAudio.mov \
 > -sws_flags bicubic -filter_complex "[0:v:0]scale='960x720'[video-
 out];[0:a]join=inputs=6,volumedetect[audio-out]" \
 > -map "[video-out]" -map "[audio-out]" -map_metadata -1 -f mp4 -vcodec
 libx264 -pix_fmt yuv420p -profile:v main -level 4.0 -map 0:a\? -b:v 5400K
 -movflags faststart -refs 4 -color_primaries bt709 -color_trc bt709
