State-Changed-Why:
    What is the correct output of your program
    supposed to be?  I tested it with gcc 3.0.1 and
    got:
    
    Build an empty Bar
    (0x0804a280) FooRef CTOR(0)
    (0xbffff6f0) Foo CTOR(0)
    (0xbffff6f0) Bar CTOR(0)
     
    New a Bar with stuff in it
    (0x0804a2a0) FooRef CTOR(1234)
    (0x0804a290) Foo CTOR(1234)
    (0x0804a290) Bar CTOR(1234)
     
    PROBLEM HERE, unbalanced Foo DTOR!!
    (0xbffff6d0) Foo Copy CTOR(1234, count:2)
    (0xbffff6d0) Bar Copy CTOR(1234)
    (0xbffff6e0) Foo Copy CTOR(1234, count:3)
    (0x0804a280) FooRef DTOR(0)
    (0xbffff6f0) Foo OP=(1234, count:4)
    (0xbffff6e0) Foo DTOR(1234, count:3)
    (0xbffff6d0) Bar DTOR(1234)
    (0xbffff6d0) Foo DTOR(1234, count:2)
     
    Destroy Bar with stuff
    (0x0804a290) Bar DTOR(1234)
    (0x0804a290) Foo DTOR(1234, count:1)
     
    End stack...
    (0xbffff6f0) Bar DTOR(1234)
    (0xbffff6f0) Foo DTOR(1234, count:0)
    (0x0804a2a0) FooRef DTOR(1234)
