boost::container::set<std::pair<int,int>>::insert cause compilation error in debug configuration in Visual Studio 2012

[anonymous]

Here is the example code

	boost::container::set<std::pair<int,int>> s;
	std::pair<int,int> p(0, 0);
	s.insert(p);

It outputs a several pages long template error starting as

1>...........\boost_1_61_0\boost/intrusive/detail/tree_value_compare.hpp(74): error C2664: 'const std::pair<_Ty1,_Ty2> &boost::move_detail::identity<T>::operator ()(const std::pair<_Ty1,_Ty2> &)' : cannot convert parameter 1 from 'const boost::container::container_detail::pair<T1,T2>' to 'const std::pair<_Ty1,_Ty2> &'

................................

Same code compiles correctly in release configuration. And it compiles correctly in boost 1.59 in all configurations.

Marking it as Showstopper as it breaks a lot of our code.

To reproduce - create a new VS2012 project with default settings. I didn't test it on other versions of Visual Studio.
