Exploration order: layer-based BFS. Considering fixpoint variant with monodirectional inclusion of symbolic zones (instead of equality). Counterexample mode: the analysis will stop as soon as a target state is found. The cartography will be drawn. The result will be written to a file. The trace set(s) will be generated in a graphical mode. Description of states will be output.  Abstract model built after 0.010 second. Memory for abstract model: 1084.597 KiB (i.e., 277657 words)  Starting running algorithm AGsafe…  Computing post^1 from 1 state. Computing post^2 from 5 states. Computing post^3 from 25 states.
