One deterministic module has affine ranking function -2 * s2 + 3 * unknown-#length-unknown[nondetString1] and consists of 10 locations. One nondeterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length2 * sizeof(char))] + -1 * s2 and consists of 6 locations. 3 modules have a trivial ranking function, the largest among these consists of 9 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 33.1s and 9 iterations.
