(If I could just understand this sentence: Is it meant as
an insult? How do you expect the issue to be fixed? By
looking at the code? Seriously?)

I can confirm that there is an issue with current musl,
it is (for example) reproducible by calling
libavutil/tests/pixelutils which crashes every time and I
can confirm that adding an emms() call to av_free()
fixes the issue.

PS: There are several unrelated build issues. Either
they only happen here (which I consider unlikely) or
there is an - unknown - reason why the OP decided
not to tell us about those.
