Hello, It looks like some general information is due:
Musl libc is a high quality standard C library for Linux with emphasis on "quality" and "standard" http://www.musl-libc.org/ On Sat, Oct 01, 2016 at 12:31:05PM -0400, Ronald S.

Not mine, but musl's. I am not involved in musl development. (The tradition of fixed-point malloc was born while floating point was extremely expensive. It is otherwise a "myth" that memory management can not have use for floating point operations. Musl malloc() is well behaving, efficient and robust.) If you are curious you may wish to look at its code (it is clean and readable).

I hope the explanation above sheds light on the matter. > In that case use emms_c() before calling those functions. Yes, it is probably what ffmpeg should do and this is the point of my report. If you mean that I should have submitted a patch, I really hope somebody else can do the actual fix(es).
