#9478: Converting an aac input to mp4 sometimes succeed but sometimes fail
-------------------------------------+-------------------------------------

-------------------------------------+-------------------------------------
Summary of the bug: When I was trying to converting an aac input to mp4,
it sometimes succeeds but sometimes fails. For a robust software, I
believe it should behave the same way regardless of success or failure.
Compiler: gcc11
How to reproduce:
{{{
% ffmpeg -threads 1 -y -i input.aac -f mp4 output.mp4
