[Bug c++/37065] New: Virtual function from member constructor and destructor

["HHG01200 at nifty dot ne dot jp" <gcc-bugzilla at gcc dot gnu dot org>]

While member objects are constructed or destructed, the owner object's
overloaded virtual function is called.
It may be a problem because the owner object is not fully constructed at these
stage.
I think it is correct if base class' virtual function is called because the
base object is fully constructed at these stage.

------------------
#include <stdio.h>

class A
{
public:
A() {printf("A::A(),  "); v();}
virtual ~A() {printf("A::~A(), "); v();}
virtual void v() {puts("A::v()");}
};

class C
{
public:
A* p;
C(A* a) : p(a) {printf("C::C(),  "); p->v();}
~C() {printf("C::~C(), "); p->v();}
};

class B : public A
{
public:
C c;
B() : c(this) {printf("B::B(),  "); v();}
~B() {printf("B::~B(), "); v();}
void v() {puts("B::v()");}
};


int main()
{
 B b;

 return 0;
}

------------------
Actual result:

A::A(),  A::v()
C::C(),  B::v()
B::B(),  B::v()
B::~B(), B::v()
C::~C(), B::v()
A::~A(), A::v()

------------------
(I think) correct result:

A::A(),  A::v()
C::C(),  A::v()
B::B(),  B::v()
B::~B(), B::v()
C::~C(), A::v()
A::~A(), A::v()
