Yes, I believe that's undefined (even if the array is part of a larger
object, as the same principle as "An array subscript is out of range, even
if an object is apparently accessible with the given subscript (as in the
lvalue expression a[1][7] given the declaration int a[4][5]) (6.5.6)."
(Annex J) applies).
