One deterministic module has affine ranking function 2 * sc1 + 18446744073709551615 * unknown-#length-unknown[__builtin_alloca(length2 * sizeof(char))] and consists of 3 locations. One deterministic module has affine ranking function 2 * s + 1 and consists of 3 locations. One nondeterministic module has affine ranking function 2 * s + unknown-#length-unknown[s2] and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 11 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 17.7s and 6 iterations.
