This definitely sounds like a compiler bug. But your code isn't quite standard-conforming. You ought to use a pointer to member, not reinterpret_cast tricks. boost::function getmem( double A::* pm ) { return pm; }

int main() { A obj; obj.a = 1.; obj.b = 2.; // foo( getmem(&obj, &obj.b), obj );

foo( getmem( &A::b ), obj );

}
