Proposed resolution:

This wording is relative to N4892.

  1. Modify [string.view.cons] as indicated:

    template<class It, class End>
      constexpr basic_string_view(It begin, End end);
    

    -7- Constraints:

    […]

    -8- Preconditions:

    […]

    -9- Effects: Initializes data_ with to_address(begin) and initializes size_ with end - begin.

    -?- Throws: When and what end - begin throws.

Set status to Tentatively Ready after eight votes in favour during reflector poll.

The standard does not specify the exceptions of this constructor, but since std::to_address is a noexcept function, this constructor throws if and only when end - begin throws, we should add a Throws element for it.
