One deterministic module has affine ranking function -1 * src + unknown-#length-unknown[__builtin_alloca(length * sizeof(char))] and consists of 4 locations. One deterministic module has affine ranking function unknown-#length-unknown[__builtin_alloca(n * sizeof(char))] + 2 * us and consists of 4 locations. - StatisticsResult: Timing statistics BüchiAutomizer plugin needed 5.6s and 3 iterations. TraceHistogramMax:1. Analysis of lassos took 5.2s. Construction of modules took 0.0s. Büchi inclusion checks took 0.2s. Highest rank in rank-based complementation 3. Minimization of det autom 2.
