Hi,

I found a problem in using boost.function with VC++ 10, the code below
reproduces the problem:

 

#include <boost/function.hpp>

#include <vector>

typedef std::vector<int> test_type;

template<class T>

struct S

{

                void test_g()

        {

            typedef S<T> this_class;            

            boost::function<void (this_class*, test_type)>
s(&this_class::g);

        }

        

        void g(test_type){}

};

 

int main()

{

    S<int> s;

    s.test_g();

}

 

This code is OK with VC++ 2008, but with VC++ 2010, it yields the
following message. 

Is there anything that I can do to solve the ambiguity? Thanks.
