Strange. The compiler message is valid. However, I looked at the problem and
tried to reduce it to its smallest form. Suprisingly, the error message 
disappeared! But, as you would it suspect, it coredumps right on cue.
So where did the error message go to?
 
#include <iostream.h>
struct b {
    virtual void g() = 0;
};

struct c : public b {
     virtual void g() { cout << "c::g()" << endl; }
};

struct e : public b {
};

struct d : public c, public e {
    virtual void g() { cout << "d::g()" << endl; }
};

main()
{
   d *D = new d;
   b *bc = (b *)((c *)D);
   b *be = (b *)((e *)D);
   D->g();
   bc->g();
   be->g();
   return 0;
}

The above code, when run, produced:

c::g()
d::g()
Abort (core dumped)
