             Bug #: 14222
           Summary: Why a formal parameter object of a function can not be
                    treated as a object reference
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement

Created attachment 9467
  --> http://llvm.org/bugs/attachment.cgi?id=9467
the test case for this problem.

I defined a function like this:
int foo( AA& a);
when i use the function like this:
int rec2 = foo(AA(1));
i compiled it but i got an error:
reference_test.cpp:18:14: error: no matching function for call to 'foo'
  int rec2 = foo(AA(1));
if i use the function like this:
  AA aa(1);
  int rec1 = foo(aa); 
it worked well.
But both method can work on VS2012,i am not sure if it is a bug or clang do it
purposely.
