[Bug 771589] Re: fbb buffer overflow
I haven't figured it out either. The setup script bombed and I had to
create the ports file from scratch, but I've gone over and over all the
configs and simplified as much as I can to eliminate potential problems,
and always get this same result after the languages are done loading.
