Sure. I'm willing to test further. I just thought that since 1) clang is the
default compiler in FreeBSD 10+ and 2) if the problem was with the default,
ancient compiler in FreeBSD 9.x, I might be abusing everyone's valuable time.

I set the FreeBSD emacs-devel port (FreeBSD package building system) to pull
from commit 44b16f6 and I still see the problem on amd64 (with X), but not on
i386.

The newer GCC was referenced because a dependency required it, however Emacs
itself was built with the default compiler (cc) which is a patched GCC 4.2.1 (as
Wolfgang stated).
