So the earlier lines are flawed too, just working by chance?

Yes, combinations of counting_range with reversed. But not because counting_range is a temporary. I think the problem is counting_iterator returns a reference to an int it owns. Iterators shouldn't do that. Iterators should either: - return a reference to something they don't own, or - return by value. Regards, Kris
