Synopsis: Err in non-virtual func name in dump class file

State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Tue Feb 18 00:04:09 2003
State-Changed-Why:
    Confirmed. The mangled name in the report allegedly
    expected at this place is
      _ZThn4_N1CIiE6v_funcEv
      non-virtual thunk [nv:-4] to C<int>::v_func()
    by the way.
    
    We get the same behavior for 3.2 through to 3.4 of today.
    However, the actual content of the vtable is correct, it
    is just the dump that is wrong.

>Description:
Sourc code for a.cpp:
------------------------------------------------
struct A { virtual void v_func(){}; };
struct B { virtual void v_func(){}; };

template <class T> struct C: public B, public A {
        C(T i) {};
        void v_func(){};
};

C<int> pc(10);
------------------------------------------------

Actual class hierarchy file (a.cpp.class):
------------------------------------------------
in line 30 of a.cpp.class
20    C<T>::v_func() [with T = int]
------------------------------------------------

Expected Behaviour:
---------------------------------------------------
in line 30 of a.cpp.class
20    C<T>::_ZThn4_N1CIiE6v_funcEv() [with T = int]
