FWIW, I have run into this on x64_64 Linux, on transcoding machines,
at work, as well.

This seems to be a rather contentious subject. Would you be amenable to
perhaps joining #ffmpeg-devel to discuss in real time? In my experience,
stuff gets cleared up a lot faster, and with few misunderstandings / large
mailing list flames/threads, for subjects like these, in such a setting.
That's just my 2 cents of course.
