Max. memory is 42.9GB. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction: - AllSpecificationsHoldResult: All specifications hold We were not able to verify any specifiation because the program does not contain any specification. - StatisticsResult: Constructed decomposition of program Trivial decomposition into one module whose termination is unknown. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 10.8s and 1 iterations. TraceHistogramMax:1. Analysis of lassos took 10.8s. Construction of modules took 0.0s. Büchi inclusion checks took 0.0s. Highest rank in rank-based complementation 0. Minimization of det autom 0. Minimization of nondet autom 0. Automata minimization No data available. 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 [0, 0, 0, 0, 0].
