I'm trying to get started with MI with 1.35.0-.

I tried this:

jclark% cat test.c
// -*- C++ -*-

#include <stdio.h>

struct A {
  virtual void foo() { fputs("A::foo()\n", stderr); }
};

struct B {
  virtual void bar() { fputs("B::bar()\n", stderr); }
};

struct C : A, B {
};

main()
{
  C *p = new C;
  p->foo();
  p->bar();
}

Is this a bug or am I just ignorant?  I wonder whether some kind
person might care to post a brief description of how MI works in G++.
