Boost 1.56.0 compilation error in iterator_range
I get a compilation error with vc10, iterator_range and a (const) unordered_map (the beta candidate 2 was still ok I think): #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. (note had to cut due to 'you have lines longer than 80 characters. Fix that.' in Gmane)

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: https://github.com/boostorg/range/commit/264017e2a9bdbfcc24517ce05f8ef96df0a... 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? Thanks, Eric
