Comment (by Kamedo2):

 This rare sample and this command induces infinite loop on the current git
 head.
 {{{
 ffmpeg73505 -i ffmpeg_aac_error1.flac -c:a aac -strict experimental -q:a 1
 -ar 8000 out.mp4
 ffmpeg73505 -i ffmpeg_aac_error1.flac -c:a aac -strict experimental -b:a
 96k -ar 8000 out.mp4
