call to int Derived::val()
 --> call to private member from constructor init list
call to void Derived::g1()
 --> public
call to void Derived::p()
 --> private in same class
call to void Base::f()
 --> protected in base
call to void Base::x()
call to void HasFriend::h()
Calls2: call to void HasFriend::h()
Calls3: call to void HasFriend::h()
 --> access for friend Base::x() only
call to void Derived::g2()
 --> public
call to void Derived::p()
 --> private in same class
call to void Base::f()
 --> protected in base
call to void Base::x()
call to void HasFriend::h()
Calls2: call to void HasFriend::h()
Calls3: call to void HasFriend::h()
