  Version:  Boost 1.49.0                              |    Severity:  Problem

 the following code fails to compile with both boost 1.47 and 1.49 (GCC
 4.4.4):
 {{{
 #include <boost/phoenix.hpp>

 class A
 {
     A(const A&);
     A& operator=(const A&);
 public:
     A() {}
     const A& operator<<(const char *p) const
     {
         return *this;
     }
 } g_a;

 int main()
 {
   ( boost::phoenix::ref(g_a) << boost::phoenix::placeholders::_1
 )("test");
 }
 }}}
 error: 'A::A(const A&)' is private

 Btw, it also doesn't work with boost::lambda::var, in the same manner.
