Exploration order: layer-based BFS. Considering fixpoint variant with bidirectional 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 0.011 second. Memory for abstract model: 890.476 KiB (i.e., 227962 words)  Starting running algorithm AGsafe…  Computing post^1 from 1 state. Computing post^2 from 3 states.  1 state merged within 9 states. Computing post^3 from 8 states.  2 states merged within 15 states. Computing post^4 from 13 states.  2 states merged within 26 states. Computing post^5 from 24 states.  [AGsafe] Found a new state violating the property.  [AGsafe] Target state found! Terminating…  Fixpoint reached at a depth of 6: 76 states with 148 transitions in the final state space.  [AGsafe] Algorithm completed after 0.123 second.
