I've mixed feelings about this.  On the one hand, I'm not sure the
current semantic is the best one, so it seems better to leave the
behaviour "unspecified"; on the other hand, this testcase is not
documentation nor public API, so fixing it would be trivial enough
in case we later decide to modify the current semantic.  Hmm...

Well, I'll just leave the decision to you and Ralf.
