A brief look at your code suggests that you have run into the same problem 
like Dave Greene:

http://article.gmane.org/gmane.comp.lib.boost.user/17091

You need wrap all inner initial states that are template instantiations into 
an mpl::list<> ...

template< typename S >
struct proto
: public sc::simple_state<
        proto< S >,
        sm< S >,
        mpl::list< inactive< S > > // *** here ***
>
{};

... and everything should work as expected.

Follow the link above for details.

HTH,
