Hi,

while playing with MSM using VS2010+SP1 in a very simple test project (I'm
really just trying to test how to organize states classes in files), I've
tried to see if I was able to create as many state machines as I wanted, so
I started to write a simple

    std::vector<MyStateMachine> state_machines(42);

Here MyStateMachine is an empty state machine class with default front-end
and back-end, with only two empty states.

VC10.1 produce a warning on this line saying that there will be a stack
overflow because there is a runtime recursion. I checked, it does crash (in
debug at least).

Is it a bug?

I've not found time yet to follow the code see why that produce a recursion
(??!!!), but in doubt I verified simple cases :

    MyStateMachine state_machine ; // no problem
    MyStateMachine state_machines[42]; // no problem

I'll post the full  code here once I get home, can't access my test project
at my dayjob.
I think it might be a well known problem so I ask here first.
