One deterministic module has affine ranking function -1 * d + unknown-#length-unknown[d] and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (out_len)] + -1 * s and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (out_len)] + -1 * s and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.5s and 5 iterations.
