One nondeterministic module has affine ranking function unknown-#memory_int-unknown[a][a + i * 4] and consists of 4 locations. 2 modules have a trivial ranking function, the largest among these consists of 11 locations. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.buchiautomizer: - ExceptionOrErrorResult: ClassCastException: class de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsAggregator cannot be cast to class de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsData (de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsAggregator and de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsData are in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @560348e6) de.uni_freiburg.informatik.ultimate.plugins.generator.buchiautomizer: ClassCastException: class de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsAggregator cannot be cast to class de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsData (de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsAggregator and de.uni_freiburg.informatik.ultimate.util.statistics.StatisticsData are in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @560348e6): de.uni_freiburg.informatik.ultimate.plugins.generator.buchiautomizer.BuchiCegarLoopBenchmark.prettyprintBenchmarkData(BuchiCegarLoopBenchmark.java:178) RESULT: Ultimate could not prove your program: Toolchain returned no result.
