193. Order of destruction of local automatics of destructor

Section: 11.4.7 [class.dtor]Status: TC1Submitter: Gerhard MenzlDate: 7 Jan 2000

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

struct S { ~S(); };

struct T {
    S x;
    ~T() {
        S y;
    };
};

which will be destroyed first, x or y?

Proposed resolution (10/00):

In 11.4.7 [class.dtor] paragraph 6, change

A destructor for class X calls the destructors forX's direct members, ...

to

After executing the body of the destructor and destroying any automatic objects allocated within the body, a destructor for classX calls the destructors for X's direct members, ...
