One deterministic module has affine ranking function -1 * i + length2 and consists of 5 locations. One deterministic module has affine ranking function -1 * to + unknown-#length-unknown[__builtin_alloca (length2 * sizeof(char))] and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.1s and 4 iterations.
