One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length * sizeof(char))] + -1 * s and consists of 5 locations. One deterministic module has affine ranking function unknown-#length-unknown[d] + -1 * d and consists of 3 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 23.6s and 3 iterations.
