If the internal error means the re engine bumped into some internal
limit and gracefully raised an exception, then fine.  If "internal
error" means the re engine unexpectedly got into some inconsistent
internal state, then threw up its hands and barfed after discovering
the error sometime later, that's bad.  Does nobody care which it is?
