Actually, I got it from n3242 which is a recent C++0x draft.

Okay. Let's do this a different way
(a little later in the section):

"In the first alternative (delete object), if the static type
of the operand is different from its dynamic type, the
static type shall be a base class of the operand’s
dynamic type and the static type shall have a virtual
destructor or the behavior is undefined."
