int &a = a;
i don't believe this is valid code.  i believe g++ should reject the code.
various comp.std.c++ people agree with me.

8.3.2/4 states "[...] A reference shall be initialized to refer to a valid
object or function."

surely a (the right-hand-side) is not a valid object or function since it has
not been initialised, so the code is ill-formed.
