C++-Standard">[...] the value of the operand of delete shall be a pointer to a non-array object created by a new-expression, or a pointer to a sub-object representing a base class of such an object. If not, the behavior is undefined.

[...] 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.
