<P>The Standard is not clear whether automatic objects in a destructor
are destroyed before or after the destruction of the class's base and
member subobjects.  That is, given</P>

<PRE>
    struct S { ~S(); };

    struct T {
        S x;
        ~T() {
            S y;
        };
    };
</PRE>

<P>which will be destroyed first, <TT>x</TT> or <TT>y</TT>?</P>

<P><B>Proposed resolution (10/00):</B></P>

<P>In 11.4.7 [<A href="https://wg21.link/class.dtor#6">class.dtor</A>] paragraph 6, change

<BLOCKQUOTE>
A destructor for class <TT>X</TT> calls the destructors for
<TT>X</TT>'s direct members, ...
</BLOCKQUOTE>

to

<BLOCKQUOTE>
After executing the body of the destructor and destroying any
automatic objects allocated within the body, a destructor for class
<TT>X</TT> calls the destructors for <TT>X</TT>'s direct members, ...
