One deterministic module has affine ranking function 2 * sc1 + 1 and consists of 3 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca(length2 * sizeof(char))] + 2 * s and consists of 4 locations. One nondeterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca(length2 * sizeof(char))] + 2 * s 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 10.6s and 6 iterations.
