Eventually someone will get to it.  I don't know if we have a FreeBSD 
machine.  If you were able to provide shell access to somebody it might 
be faster.  Anyway, can you try

./configure --enable-debugging-features --with-threading=switch

?

I have no idea either, but it's apparently another threading bug.  If 
you have linuxthreads available for FreeBSD and it's not a pain to use 
them, that would be worth trying out.
