To remove any doubt about this I've replaced the previous code with the
following one:
 
  int num_of_agents=[agentsList getCount];

  for (instant=0; instant< num_of_agents ; instant++)
     [simulationSchedule at: instant createActionTo:
             [agentsList atOffset: instant]  message: M(evalSignals)];

but the error doesn't go away. Perhaps could help to know that the event is
raised just after '[[self getActivity] terminate]' in - ckeckToStop method;
here's gdb output:

289 [[self getActivity] terminate];
(gdb)n

I can only make guesses: it seems like the problem resides in [[self
getActivity] terminate].Couldn't that message be referred to the schedule
rather than to the list of agents?
