10336,compilation error in iterator_range and unordered_map,gast128@…,Neil Groves,"I get a compilation error with vc10, iterator_range and a (const)
unordered_map (the beta candidate 2 was still ok I think):

{{{#!cpp
#include ""stdafx.h""
#include <boost/range/iterator_range.hpp>
#include <boost/unordered_map.hpp>


int _tmain(int /*argc*/, _TCHAR* /*argv*/[])
{
   typedef boost::unordered_map<int, int>            Container;
   typedef Container::const_iterator                 ContainerIterator;
   typedef boost::iterator_range<ContainerIterator>  ContainerIteratorRange;

   const Container cnt;

   ContainerIteratorRange rng(cnt.cbegin(), cnt.cend());
   
   return 0;
}
}}}

This gives C2248: 

'boost::unordered::iterator_detail::c_iterator<Node,ConstNodePointer>::iterator'

cannot access private typedef declared in class

etc.


Eric: Niebler:

Well, this is unfortunate. It's broken also on msvc-12 and clang trunk,
but strangely not on gcc. I thought it might be due to this change in
Boost.Range:

github.com/boostorg/range/commit/264017e2a9bdbfcc24517ce05f8ef96df0a8c45b

But reverting that doesn't have any effect. It works on Boost 1.55, so
this is definitely a regression.

Can you please file a bug? Neil, can you take a look?

A possible fix:
github.com/boostorg/range/pull/19
