Range + fixed_string

18 Aug 2005

      I have a project that uses the fixed_string library (which is still in the 
review que).

This library worked fine with string_algo in boost 1.32 but not with boost 
1.33. I traced the problem to be the following

template <typename StringT> 
struct C {
  typedef range_result_iterator<StringT>::type range_iterator_type;
  typedef StringT::iterator iterator_type;
  BOOST_STATIC_ASSERT((is_same<range_iterator_type, iterator_type>::value));
  int dummy;
};

main() {
  C<std::string>     a; // ok
  C<array<char, 5> > b; // ok
  C<const_string<> > c; // ok
  C<vector<char> >   d; // ok
  C<fixed_string<10> > e; // static assert
}

Didn't find any obvious reason in any of the libraries involved. Is it a 
problem with the VC70 compiler?

(Also noticed that the range library copied a lot from the string_algo library 
e.g. BOOST_STRING_TYPENAME and code layout. Doesn't matter but it confused me 
sometimes about what library source I was looking at)
