 Summary of the bug:
 so i get a strange bug where ffmpeg crashes from time to time.
 this especially happens when i use a resolution of 1024x576.

 i have a sample here which includes a bat file with the command, the video
 file and the ffmpeg version.
 https://sharing.rainbowdash.cc/testencode_short.7z
 i also have the video file separate here:
 https://sharing.rainbowdash.cc/ffmpegbug/input_short.mkv

 it crashes just before the credits begin.
 i tested it both on a ryzen system and an older intel system, on windows
 10 (64bit).
 both produce this error. maybe its a problem of my command line, but i
 think ffmpeg should maybe prevent this command then.

 How to reproduce:
 {{{
 ffmpeg -i "input_short.mkv" -map_metadata -1 -map 0:v -map 0:a:1 -c:v
 libaom-av1 -strict experimental -vf "scale=1024:576" -cpu-used 5 -crf 48
