I changed it to call the function. Still works.

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

#ifdef BOOST_NO_CXX11_RVALUE_REFERENCES
#error
#endif

struct A
{
    void f( int& x, std::vector<int*>& v )
    {
        v.push_back( &x );
    }
};

int main()
{
    A a;
    auto f = boost::bind(&A::f, &a, _1, _2);

    int x;
    std::vector<int*> v;

    f( x, v );

    std::cout << &x << "; " << v.front() << std::endl;
}

Output:
