--- Comment #1 from Pedro F. Giffuni <pfg at FreeBSD.org> ---
The bug is still present in FreeBSD 9.3's gcc. The bug is not present with the
bundled clang though.

Unfortunately we don't plan to do major updates to the gcc version available in
the FreeBSD 9.x series: 10.x and newer ship with clang by default. Please use
clang or the gcc version from ports which should be a lot more up to date.
