4544	shared_ptr seems to be mistake in unordered_set	showern <showern@…>	Daniel James	"class Abc
{
};

int main()
{
    boost::shared_ptr a(new Abc);
    boost::shared_ptr b(new Abc);
    unordered_set<shared_ptr<Abc> > xx;
    xx.insert(a);
    xx.insert(b);

    // always get 1 here, 
    cout << xx.hash_function()(a) << "" "" << xx.hash_function() 
    << endl;

    return 0;
}

judging two objects pointed by shared_ptr should compare the address of them, but how hash_function() always returns 1?
