Max. memory is 16.1GB. * Results from de.uni_freiburg.informatik.ultimate.plugins.generator.traceabstraction: - StatisticsResult: Constructed decomposition of program Your program was decomposed into 6 terminating modules (3 trivial, 3 deterministic, 0 nondeterministic). One deterministic module has affine ranking function -1 * i + in_len and consists of 5 locations. One deterministic module has affine ranking function out_len + -1 * i and consists of 4 locations. One deterministic module has affine ranking function -1 * s2 + unknown-#length-unknown[__builtin_alloca (in_len)] and consists of 5 locations. 3 modules have a trivial ranking function, the largest among these consists of 8 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 10.1s and 7 iterations. TraceHistogramMax:1. Analysis of lassos took 9.0s. Construction of modules took 0.1s. Büchi inclusion checks took 0.7s. Highest rank in rank-based complementation 3. Minimization of det autom 6.
