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 2 terminating modules (0 trivial, 2 deterministic, 0 nondeterministic). One deterministic module has affine ranking function 2 * src + unknown-#length-unknown[__builtin_alloca(length * sizeof(char))] and consists of 4 locations. One deterministic module has affine ranking function 2 * us + unknown-#length-unknown[__builtin_alloca(n * sizeof(char))] and consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 7.9s and 3 iterations.
