Detailed Description
   template<typename _Iterator, typename _Sequence, typename _Category =
       typename std::iterator_traits<_Iterator>::iterator_category>
       class __gnu_debug::_Safe_iterator< _Iterator, _Sequence, _Category
       >"Safe iterator wrapper.

       The class template _Safe_iterator is a wrapper around an iterator that
       tracks the iterator's movement among sequences and checks that
       operations performed on the 'safe' iterator are legal. In additional to
       the basic iterator operations (which are validated, and then passed to
       the underlying iterator), _Safe_iterator has member functions for
       iterator invalidation, attaching/detaching the iterator from sequences,
       and querying the iterator's state.

       Note that _Iterator must be the first base class so that it gets
       initialized before the iterator is being attached to the container's
       list of iterators and it is being detached before _Iterator get
       destroyed. Otherwise it would result in a data race.

   unsigned int __gnu_debug::_Safe_iterator_base::_M_version [inherited]
       The version number of this iterator. The sentinel value 0 is used to
       indicate an invalidated iterator (i.e., one that is singular because of
       an operation on the container). This version number must equal the
       version number in the sequence referenced by _M_sequence for the
       iterator to be non-singular.
