Confirmed.  Reduced testcase:

#include <iostream>
#include <vector>
template< class Iter, class Aggregator > 
inline typename Aggregator::value_type 
aggregate( Iter first, Iter second, Aggregator p_arg ) {
};
template< class A, class V > struct sum_equals {
    typedef V value_type;
};
template< class FUNC > class unary_aggregator {
public:
    typedef FUNC functor_type;
    typedef typename functor_type::value_type value_type;
    unary_aggregator( const value_type & p_init = value_type(),                
                      const functor_type & p_func = functor_type() )     
        :m_value(p_init), m_functor(p_func){
    }
    value_type m_value;
    functor_type m_functor;
};
template< class A, class V > struct accumulate 
: public unary_aggregator< sum_equals< A, V > > {
    accumulate( const V & p_arg = V() )
        :unary_aggregator< sum_equals< A, V > >( p_arg ){
    }
};
int main( int, char ** ) {
    std::vector< float > c_args(3);
    std::cout << aggregate( c_args.begin(), c_args.end(), 
                            accumulate<float, float>(0) ) << std::endl;
}
