[Boost-users] [statechart] No state?

Hi,

I'm implementing an asynchronous state machine and have problems with events 
not being dispatched. All event thrown at the fsm are dispatched to the 
unhandled_event method.

When debugging the problem, I used typeid on the event to see that the 
expected events were generated (they were) from the event dispatch threads. 
After this, I tried to get the current state from within the 
unhandled_event() method - but to my surprise the statement 
"this->state_begin() != this->state_end()" is never satisfied. Looks like 
there's no current state.

What's even more confusing is that this behaviour is only exposed in the 
application itself. This part of the project is divided into three modules; 
the application, a static library containing most of the code, and a unit 
test driver. The test driver and the application links to the library. When 
running the unit tests, the dispatching works and it is possible to see the 
current state using the above method. Release or debug mode doesn't matter. 
RTTI is enabled.

Using RC_1_34_0 and VC8. What could possibly expose this behaviour?
