Reopening this bug as the fact that a copy constructor is being called is
irrelevant if the construction is not, in fact, copy construction. p31 is
applicable only during copy/move construction. See also CWG535 [1] which
clarifies that elision can be applied to constructors other than copy and move
constructors if they are selected to perform a copy or move operation, and was
applied to the working draft at Kona.
