This commit avoids overflow in index input slices invariant checks.

While not a problem in practice, this can lead to more obscure failures which are harder to diagnose. Reworking the invariant checks to avoid the potential to overflow is trivial. Existing tests cover the most cases, while a single new scenario covered the overflow case.
