Comment(by anonymous):

 The problem with your code is that you are including the Spirit headers
 files independently and before including Wave. Wave enables Spirit thread
 safety whenever it is compiled in multi-threaded mode. But if you include
 Spirit before Wave you need to switch Spirit (and probably Phoenix) into
 multi-threaded mode yourself. I was able to run your example successfully
 by adding:
 {{{
 #define BOOST_SPIRIT_THREADSAFE 1
 #define PHOENIX_THREADSAFE 1      // needed only if you use Phoenix
 }}}

 to your stdafx.h before including Spirit.
