One deterministic module has affine ranking function -1 * i + unknown-#length-unknown[nondetString1] and consists of 5 locations. One deterministic module has affine ranking function -1 * i + length2 and consists of 4 locations. One deterministic module has affine ranking function -1 * sc1 + unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[nondetString1] + -1 * s and consists of 10 locations.
