2775. reverse_iterator is does not compile for fancy pointers

Section: 24.5.1.6 [reverse.iter.elem] Status: Dup Submitter: Billy Robert O'Neal III Opened: 2016-09-23 Last modified: 2021-06-06

Discussion:

std::reverse_iterator<Iterator>::operator->() is specified to call addressof(operator*()), but it returns iterator_traits<Iterator>::pointer, which may be a fancy pointer type from which no conversion from T* is possible. It should instead delegate to the underlying iterator's operator->().

Set status to Duplicate

Proposed resolution:

This wording is relative to N4606.

Modify [reverse.iter.opref] as indicated:
```
constexpr pointer operator->() const;
```
-1- Returns: addressof(operator*()). Effects: If Iterator is a pointer type, as if by:
```
Iterator tmp = current;
return --tmp;
```
Otherwise, as if by:
```
Iterator tmp = current;
--tmp;
return tmp.operator->();
```
