--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note most of the rest of the paragraphs around it say "If the value of the operand of the delete-expression is not a null pointer value and .." The question becomes is that an oversight of P3144R2 or not and should a null pointer constant be valid always since that was never undefined or even had a chance of being undefined. Yes it is bad coding but still.
