--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
-fdelete-null-pointer-checks is generally an option that tells whether it is
possible to have objects at address 0 (-fno-delete-null-pointer-checks) or not.
So the use above seems to be correct.
Anything can happen on UB and NULL pointer dereference is UB, so I don't see
why you expect anything in particular.
