One deterministic module has affine ranking function (array_size + ((long) -1 * i)) and consists of 3 locations. One deterministic module has affine ranking function ((__int128) 18446744073709551609U + ((long) -4 * j)) and consists of 4 locations. One nondeterministic module has affine ranking function null and consists of 5 locations.
