Proposed resolution:

This wording is relative to N3936.

  1. Change [util.smartptr.getdeleter] as indicated:

    template <class D, class T> get_deleter(const shared_ptr<T>& p) noexcept;

    -1- Returns: If p owns a deleter d of type cv-unqualified D, returns &std::addressof(d); otherwise returns 0nullptr. […]

The Standard Library should consistently use addressof() to defend itself against overloaded operator&().

While we're in the neighbourhood, we should editorially change 0 to nullptr.
