New description:

 This program fails:
 {{{
 #!c++
 #include <boost/phoenix.hpp>
 #include <boost/range/as_literal.hpp>

 using namespace boost::phoenix::placeholders;
 using namespace boost::phoenix;

 int main()
 {
     find(boost::as_literal("fox"), 'x')();                      // works
     find(boost::as_literal("fox"), construct<char>(arg1))('x'); // works
     find(boost::as_literal("fox"), arg1)('x');                  //
 compilation error
 }
 }}}

 Took hours to work out what was going on.  Nature of the beast, I suppose.
