One deterministic module has affine ranking function -4 * i + unknown-#length-unknown[__builtin_alloca (array_size * sizeof(int))] and consists of 5 locations. One deterministic module has affine ranking function -1 * pass + n and consists of 3 locations. One deterministic module has affine ranking function -4 * i + unknown-#length-unknown[x] and consists of 6 locations. One nondeterministic module has affine ranking function -1 * x + -4 * i + 27670116110564327411 and consists of 10 locations. One nondeterministic module has affine ranking function -1 * pass + n + -1 * i and consists of 4 locations. 7 modules have a trivial ranking function, the largest among these consists of 21 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 22.1s and 13 iterations.
