According to [dcl.init.ref], p5 of the latest working paper (N2960), 

    A reference to type “cv1 T1” is initialized by an expression of type
    “cv2 T2” as follows:
    ...

    ...the reference shall be an lvalue reference to a non-volatile const
    type (i.e., cv1 shall be const), or the reference shall be an rvalue
    reference and the initializer expression shall be an rvalue.

The following ill-formed program is accepted by gcc 4.4.1:

$    cat u.cpp && gcc -dumpversion \
  && gcc -W -Wall -c -std=c++0x u.cpp && echo FAIL
extern int &ir;
int &&irr = ir;   // ill-formed
4.4.1
FAIL

------- Comment #1 from paolo dot carlini at oracle dot com  2009-10-10 22:36 -------
This is already fixed in mainline, I don't know whether there are plans to back
port to 4_4-branch...

No, I'm not planning to fix this in 4.4.
