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[__builtin_alloca (length2 * sizeof(char))] and consists of 5 locations. One deterministic module has affine ranking function -1 * append + unknown-#length-unknown[nondetString1] and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[s] + -1 * s and consists of 3 locations. 2 modules have a trivial ranking function, the largest among these consists of 9 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.7s and 7 iterations.
