Of course, and of course. But that has nothing to do with my reduced snippet,
which is equivalent to our standard-conforming implementation of std::auto_ptr,
as far as I can see, and, does compile, whereas it should not - to be clear, I
think you are therefore right, just there is nothing wrong with our
implementation of std::auto_ptr, if anything, this is a front-end issue. By the
way, ICC rejects my reduced snippet.
