Windows 2000, CygWin 1.1.8
>Description:
According to ISO 14882:1998, paragraph 6.6/2: "On exit from scope
(however accomplished), destructors are called for all constructed
objects with automatic storage duration (named objects or temporaries)
that are declared in that scope, in the REVERSE order of their
declaration."  You will note that the objects 3 and 4, above, are
destructed in the order of their declaration, not the reverse order.
>How-To-Repeat:
Compile function with:
    g++ --verbose orderdtors.cc -o order
Then execute program with
    order
Output is
A::A(): 1
B::B(): 2
A::A(A): 3
B::B(B): 4
A::~A(): 3
B::~B(): 4
B::~B(): 2
A::~A(): 1

The fourth and fifth lines should be inverted.
