One deterministic module has affine ranking function -1 * i + unknown-#length-unknown[nondetString1] and consists of 5 locations. One deterministic module has affine ranking function length2 + -1 * i and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] + -1 * ps and consists of 4 locations. One deterministic module has affine ranking function -1 * pt + unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] and consists of 6 locations. One nondeterministic module has affine ranking function unknown-#length-unknown[ps] + -1 * ps2 and consists of 5 locations. 4 modules have a trivial ranking function, the largest among these consists of 27 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 31.5s and 10 iterations.
