The "parameter adjustment" above is explicitly listed as undefined
behavior, in annex J2 of n2596.pdf (for example):
"Addition or subtraction of a pointer into, or just beyond, an array
object and an integer type produces a result that does not point into,
or just beyond, the same array object (6.5.6)."

Read it again: note the qualification “that does not point into, or
just beyond, the same array object”. So long as it *does* point “into,
or just beyond, the same array object”, it is fine.
