- TimeoutResultAtElement [Line: 214]: Timeout (TraceAbstraction)
Unable to prove that call of __VERIFIER_error() unreachable (line 214). Cancelled while BasicCegarLoop was constructing difference of abstraction (3164states) and FLOYD_HOARE automaton (currently 22 states, 18 states before enhancement), while ReachableStatesComputation was computing reachable states (9767 states constructedinput type IntersectNwa).
