One deterministic module has affine ranking function length1 + -1 * i 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 * s2 + unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] and consists of 6 locations. 2 modules have a trivial ranking function, the largest among these consists of 9 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.7s and 6 iterations.
