I'm still a novice with bind but I think you have to bind twice:

#include <iostream>
#include <functional>
#include <algorithm>

#include <boost/bind.hpp>
using std::cout;
using std::endl;
using std::equal_to;

class A
{
 int i_;
public:
 int test() {return i_;}
};

class B
{
  A _a;
public:
  A& getA() {return _a;}
};

int main()
{
    B b;

    cout << (1 == boost::bind(&A::test,
            boost::bind(&B::getA, &b))()) << endl;
    return 0;
}
