Comment (by John Fletcher <J.P.Fletcher@…>):

 With further testing I have shown that the following code does NOT show
 the error with gcc 4.6 and gcc 4.8.2.  Clang 3.4 also works.
 {{{
 #include <sstream>
     std::ostringstream out;
     (
         out << phx::val("("),
         phx::for_each(arg1, phx::lambda[out << arg1]),
         out << phx::val(")")
     )(v);
     std::cout << out.str() << std::endl;
 }}}
 I don't have an explanation for why it doesn't work with {{{std::cout}}}.
 Would you please test with MSVC and see if this works for that as well.
