--- Comment #5 from Rich Felker <bugdal at aerifal dot cx> ---
My understanding is that C2x is fixing this underspecification and will require
the library functions to drop excess precision as if they used a return
statement. So this really should be fixed in glibc if it's still an issue; if
they accept fixing that I don't think GCC needs any action on this. I just
fixed it in musl.
