That's not mechanical checking, because it is a runtime check that requires a
test case that would actually trip it. Without a careful, manually created test
suite, it does not detect anything. AS is not present in the shipped product.
AS is a hackish workaround for the failure of the language to prevent such
things.
AS is just a more modern valgrind, which has been around for ages, and has
failed to turn C/C++ into memory safe languages.
