I just tried building the Git trunk on FreeBSD 10.0-CURRENT too, and I
can verify that the same thing happens.  I'm trying now after setting
the stack user-limit to limit the number of frames.

I configured Emacs with:

    ./configure --prefix=/opt/gnu --without-x

I will report any findings once I have a better backtrace.
