While that's true for the usual "p + n goes over the limit", I really
can't imagine an architecture where "p1 - p2" is valid C code (i.e. both
p1 and p2 point inside the same object) and works before `free` yet it
doesn't give the same answer after `free`.

PS: Of course, I would not be surprised to hear that there's some
compiler out there which tries to be too clever for its own sake and
will go "oh, oh, this is not allowed by the C standard, so let's
compile this into utter nonsense just so SPEC runs 0.01% faster".
