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. Merging technique of [AFS13] enabled. 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 0.009 second. Memory for abstract model: 1086.160 KiB (i.e., 278057 words)  Starting running algorithm AGsafe…  Computing post^1 from 1 state. Computing post^2 from 5 states.  6 states merged within 25 states. Computing post^3 from 19 states.  26 states merged within 85 states. Computing post^4 from 59 states.  87 states merged within 260 states. Computing post^5 from 173 states.  [AGsafe] Found a new state violating the property.  [AGsafe] Target state found! Terminating…  Fixpoint reached at a depth of 6: 675 states with 1091 transitions in the final state space.
