Re: c++/8117: member function pointers and multiple inheritance

[bangerth]

Old Synopsis: Ambiguous base for multiple inheritance with pure virtual base
New Synopsis: member function pointers and multiple inheritance

State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Mon Nov  4 14:58:17 2002
State-Changed-Why:
    Right, this is a regression since it did compile with 2.95.
    Thus, priority "high". However, present CVS compiles it
    right.
    
    Code in question:
    ------------------------------
    struct A {
        virtual void a() = 0;
    };
    
    struct B : A {};
    struct C : A {};
    
    struct D : B, C {
        virtual void a() {}
    };
    
    void (D::*s_fxn)() = &D::a;
    -------------------------------
