--- Comment #8 from Martin Sebor <msebor at gcc dot gnu.org> ---
It might be reasonable but it isn't possible to distinguish one from the other.
 The value of s has been folded into a constant by the time the warning is
issued, and its origin is lost.  In both cases the warning code sees something

  <integer_cst 0x7fffefb9d948 type <pointer_type 0x7fffefb95930> constant 0>

It's the same consequence of r254930 as bug 87041.
