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.

1. Modify [reverse.iter.opref] as indicated:

   constexpr pointer operator->() const;
   

   -1- Returns: addressof(operator*()).
