I know where the confusion is.
I don't think that the last statement is technically correct.
The fact that the client catches the exception doesn't
guarantee that the state objects are destructed.

fsm::state_machine<...> machine;
try
{
   machine.initiate();
}
catch(...)
{
   ...
}

OR

try
{
   fsm::state_machine<...> *m = new fsm::state_machine<...>();
   m->initiate();
}
catch(...)
{
   ...
}

Do you mean when the state machine object
goes out of scope or deleted?
