[Boost-users] [boost-users][StateChart] failure during termination

Hello,

When trying to terminate an asynchronous_state_machine I get the error
message: "Expression: list iterator not decrementable".
This occures in state_machine::terminate_impl( state_base_type &
theState, bool performFullExit ) in the line: else if (
currentStates_.begin() == --currentStatesEnd_ ), when trying to
perform --currentStatesEnd_, as currentStatesEnd_== 0xcdcdcdcd (i.e.
uninitialized). theState == outermost state of the machine.

I believe the problem is actually somewhere in my own code, so my
question is what it could be, according to the above symptom?

I request the termination in the following way:

struct ServerImpl
{
  //....
  shared_ptr<state_chart::fifo_scheduler<> > sessionScheduler_;
  state_chart::fifo_scheduler<>::processor_handle sessionProcessor_;
  ~ServerImpl()
  {
    // the scheduler resides in some pool, so it continues living
after ~ServerImpl
    sessionScheduler_->terminate_processor(sessionProcessor_);
  }

Thank you,

Igor'.
