// { dg-do run }
// Shows that problem of initializing one object's secondary base from
// another object via a user defined copy constructor for that base,
// the pointer for the secondary vtable is not set after implicit
// copying of the outer class, but rather has the pointer to the main
// vtable for the secondary base left over from the user defined copy
// constructor for that base.
// Correct answer is B::beefy.
// g++ prints A::beefy, which is wrong. Cfront gets it right.
