           Summary: Forwarding 0 as a pointer using rvalue references
                    doesn't work
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: enhancement

std::pair in c++0x has additional constructor overloads which take rvalue
references and forward them to the stored type's constructors. Rvalue
references forward 0 as an int rather than as a pointer. nullptr can be used to
solve this problem, but since that is not universally supported,
static_cast'ing the 0 to the expected pointer type is sufficient.
