One deterministic module has affine ranking function -1 * i + unknown-#length-unknown[nondetString1] and consists of 5 locations. One deterministic module has affine ranking function -1 * p + unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] and consists of 4 locations. 1 modules have a trivial ranking function, the largest among these consists of 7 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.0s and 4 iterations. TraceHistogramMax:1. Analysis of lassos took 4.4s. Construction of modules took 0.0s. Büchi inclusion checks took 0.3s. Highest rank in rank-based complementation 3. Minimization of det autom 3. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 2 MinimizatonAttempts, 1 StatesRemovedByMinimization, 1 NontrivialMinimizations. Non-live state removal took 0.0s Buchi closure took 0.0s. Biggest automaton had -1 states and ocurred in iteration -1. Nontrivial modules had stage [2, 0, 0, 0, 0].
