Different projects have different conventions for this. In
Subversion, we seem to have decided that it's okay for code to seg
fault in "can't happen" situations, because if the can't-happen ever
*does* happen, it's a bug we must fix anyway :-). A verbose error and
exit would only be marginally friendlier to the user -- it wouldn't
really get them any closer to a completed operation than the seg fault
