That's often a matter of taste. Once you grasped the C pointer
semantics, I usually find
foo + i
much easier to parse than
&foo[i].
Both expressions are always equivalent.
Of course,
*(foo + i)
is terrible, because
foo[i]
is much clearer then.
Anyway, for the compiler, it should never make any difference, because
these expressions are identical in their effect. If the compiler can
(statically) bounds-check &foo[i], I don't see why it would not be
able doing so for foo + i. (Most of the time, it cannot check it
though.)

Never trust an operating system you don't have sources for. ;-)
