One deterministic module has affine ranking function -1 * s + unknown-#length-unknown[__builtin_alloca (length2 * sizeof(char))] and consists of 5 locations. One deterministic module has affine ranking function -1 * s + unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] and consists of 4 locations. One deterministic module has affine ranking function -1 * s2 + unknown-#length-unknown[nondetString1] and consists of 9 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length2 * sizeof(char))] + -1 * s2 and consists of 5 locations. One nondeterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length2 * sizeof(char))] + -1 * s2 and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 15 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 18.9s and 9 iterations.
