It would be interesting to know the stack trace for this to know from where
the call is being made.  This suggests that the order of destruction is
different than what the library expects.  So other informaition
such as compiler version etc are also interesting.

Hi,

I have an assert when exiting my application using the serialization lib of 
boost 1.38.

    BOOST_DLLEXPORT static T & get_instance() {
        static detail::singleton_wrapper<T> t;
        // refer to instance, causing it to be instantiated (and
        // initialized at startup on working compilers)
        assert(! detail::singleton_wrapper<T>::m_is_destroyed);
        use(instance);
        return static_cast<T &>(t);
    }

The same code doesn't assert on windows XP so I guess that's something messy 
with static allocation on the iphone platform.
On the iphone, the load/save code works well as long as it's not called when 
the application exit.

As far I as I understand, I need to move my exit code somewhere else, when 
those singleton are still allocated.
Can somebody confirm that? Or maybe I'm missing something...

Any feedback warmly welcome!

thanks
