Topic: Destructing pointers

Hi,
the CD2 says that "the value of a pointer that refers to deallocated
storage is indeterminate". AFAIK this means that any use of the
pointer's value results in undefined behaviour. Now, 5.2.4 [expr.pseudo]
describes the syntax used to call destructors on objects of scalar type
and says: "The only effect is the evaluation of the postfix expression
before the dot or arrow". Does this mean that explicitly calling a
destructor on a deleted pointer using the dot notation like in the
example below results in undefined behaviour?
typedef int *I;
I p = new int;
delete p;
p.I::~I();
Bye
