Comment:

 In fact, under Clang with C++11, this program fails to compile:

 {{{
 #!c++
 #include <utility>
 #include <boost/spirit/home/support/multi_pass.hpp>
 #include <iterator>
 #include <boost/mpl/assert.hpp>
 #include <boost/type_traits/is_reference.hpp>
 #include <boost/type_traits/is_same.hpp>

 typedef boost::spirit::multi_pass<
     std::istreambuf_iterator<char>,
     boost::spirit::iterator_policies::default_policy<
         boost::spirit::iterator_policies::first_owner
       , boost::spirit::iterator_policies::ref_counted
       , boost::spirit::iterator_policies::buffering_input_iterator
     >
 > iterator;

 BOOST_MPL_ASSERT((
     boost::is_same<
         std::iterator_traits<iterator>::iterator_category
       , std::forward_iterator_tag>
 ));

 BOOST_MPL_ASSERT((
   boost::is_reference<std::iterator_traits<iterator>::reference>
 ));

 int main() {}
