3// another object via a user defined copy constructor for that base,
4// the pointer for the secondary vtable is not set after implicit
5// copying of the outer class, but rather has the pointer to the main
6// vtable for the secondary base left over from the user defined copy
7// constructor for that base.

9// Correct answer is B::beefy.
10// g++ prints A::beefy, which is wrong.  Cfront gets it right.
