Comment:

 I suggest you use Phoenix-3 instead. It is in the Boost trunk. The problem
 here is that Phoenix-2 has a old and flaky result-type deduction scheme.
 Phoenix-3 is better. The changes required are minimal. First use the
 proper includes:

   #include <boost/phoenix/core.hpp>
   #include <boost/phoenix/operator.hpp>
   #include <boost/phoenix/function.hpp>

 Then, change the result-of of error_function3:

     typedef OutputType result_type;

 With the changes, I am getting:

   Should be the same: 2 =? 2
   2
