Max. memory is 11.5 GB. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.cacsl2boogietranslator: - GenericResult: Unfinished Backtranslation unknown boogie variable #length * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction: - StatisticsResult: Constructed decomposition of program Your program was decomposed into 2 terminating modules (1 trivial, 1 deterministic, 0 nondeterministic) and one module whose termination is unknown.One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca (length1 * sizeof(char))] + -1 * p and consists of 3 locations. 1 modules have a trivial ranking function, the largest among these consists of 2 locations. The remainder module has 14 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 22.4s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 21.9s.
