One deterministic module has affine ranking function -1 * src + unknown-#length-unknown[__builtin_alloca(length * sizeof(char))] and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca(n * sizeof(char))] + -1 * us and consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 9.9s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 9.3s. Construction of modules took 0.0s. Büchi inclusion checks took 0.4s. Highest rank in rank-based complementation 3. Minimization of det autom 2. Minimization of nondet autom 0. Automata minimization 0.0s AutomataMinimizationTime, 1 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].
