On my x86 system, I've been seeing similar warnings being generated by
clang when compiling the ffmpeg that comes with chromium.
I've also hit another bug related to that, where clang compilation
terminates with an error message along the lines of there being not
enough registers available.
There's a bug registered for that in chromium bugzilla, which I can't
reference at the moment. So far, no solution has been implemented, as
far as I could tell.
