### 2324. Insert iterator constructors should use `addressof()`

Section: 25.5.2.2.1 [back.insert.iter.ops], 25.5.2.3.1 [front.insert.iter.ops], 25.5.2.4.1 [insert.iter.ops] Status: C++14 Submitter: Stephan T. Lavavej Opened: 2013-09-21 Last modified: 2021-06-06

Discussion:

[back.insert.iter.cons]/1, [front.insert.iter.cons]/1, and [insert.iter.cons]/1 say "Initializes container with `&x`", which doesn't defend against containers overloading `operator&()`. Containers are now required to have such defenses for their elements, so we may as well be consistent here.

[Issaquah 2014-02-11: Move to Immediate]

Proposed resolution:

This wording is relative to N3691.

1. Edit [back.insert.iter.cons]/1 as indicated:

   >     explicit back_insert_iterator(Container& x);

   > > -1- Effects: Initializes `container` with `&xstd::addressof(x)`.

2. Edit [front.insert.iter.cons]/1 as indicated:

   >     explicit front_insert_iterator(Container& x);

   > > -1- Effects: Initializes `container` with `&xstd::addressof(x)`.

3. Edit [insert.iter.cons]/1 as indicated:

   >     insert_iterator(Container& x, typename Container::iterator i);

   > > -1- Effects: Initializes `container` with `&xstd::addressof(x)` and `iter` with `i`.
