One deterministic module has affine ranking function unknown-#length-unknown[sc1] + -1 * sc1 and consists of 3 locations. One deterministic module has affine ranking function length2 + -1 * s and consists of 4 locations. One nondeterministic module has affine ranking function -1 * s + unknown-#length-unknown[__builtin_alloca(length2 * sizeof(char))] and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 10.7s and 6 iterations.
