I reported this bug first in ffmpeg because I think maybe there are some
undefined behaviors or optimizations that trigger this difference between
gcc and clang.
Is that possible that anyone can give me more details of this bug? Then
maybe we can decide whether it is a compiler bug or there are some
undefined behaviors in ffmpeg.
