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 #include

int _tmain(int /*argc*/, _TCHAR* /*argv*/[]) { typedef boost::unordered_map 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::iterator'

cannot access private typedef declared in class

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
