I sincerely appreciate that you are taking the effort to talk to me
and explain your position.

Unfortunately in your messages you consistently ignored a crucial point
and this is the last time I try to retell it:

Which you answer with

Once again, musl has absolutely no reason to change its code,
their code is well done and fully compliant.

Their responsibility is rather to the contrary, _not_ to make changes
which would hide sneaky bugs in applications. UB is a quite hideous bug.

You can not just "call musl on x86-32 unsupported", the only honest option
is to document that ffmpeg is not compliant/safe.

The problem is not in musl.
Last time in this discussion let me try to make this fact understood:

Musl merely showed you the problem and now you are suggesting to "document
that the messenger with his bad news about our health is no longer welcome".

This sounds very reasonable.
