I think you answered your own question. I vaguely remembered
that auto_ptr is an STL collection would fail because of
ownership issues when being copied (auto_ptr, IIRC, transfers
ownership when assigned, so it does not actually duplicate
but gives (mv rather than cp), so the original collection
will now hold invalid data). That's what I think I remember,
I think I got the actual fully explained reason in one of
Scott Meyer's books, but it's quite fuzzy now, so I could be
utterly wrong.
