One deterministic module has affine ranking function length1 + -1 * i and consists of 5 locations. One deterministic module has affine ranking function -1 * i + unknown-#length-unknown[nondetString2] + -1 * nondetString2 and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length2 * sizeof(char))] + -1 * spanp and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] + -1 * p and consists of 4 locations. One nondeterministic module has affine ranking function -1 * spanp + p and consists of 10 locations. One nondeterministic module has affine ranking function -1 * spanp + unknown-#length-unknown[nondetString2] and consists of 4 locations. 3 modules have a trivial ranking function, the largest among these consists of 15 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 24.1s and 10 iterations.
