Perfect forwarding doesn't seem to work quite correctly with boost::make_shared. The attached program, which tries to pass a move-only type through make_shared fails to compile with gcc in c++0x mode. To fix it, I had to change the definition of detail::forward in make_shared.hpp to use rvalue references: #if defined( BOOST_HAS_RVALUE_REFS ) template< class T > T&& forward( T &&t ) { return t; } #endif This is just based on looking at how gcc implements std::forward. Is this the right fix?
