Well considering that the following also yields different results on MSVC7.1 and gcc 3.2/3.3 I would wonder if there is a problem with one of the compilers

#include <iostream>
#include <boost/bind.hpp>

        struct X
        {
                void f() {std::cout << "None" << std::endl;}
                void f() const {std::cout << "const" << std::endl;}
        };

        template <typename T>
        void
        run( void (T::*f_)(), T& t_)
        {(t_.*f_)();}

        template <typename T>
        void
        run( void (T::*f_)() const, T const& t_)
        {(t_.*f_)();}

        int main()
        {
                X x;
                run(&X::f,x);
                boost::bind(&X::f,_1)(x);
        }

Well, that is a different matter. If one might want to follow Andrei's suggestion of using volatile to encapsulate synchronisation then they are still worthwhile. (CUJ February 2001).
