--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> --- The code is well-formed according to http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#106 but that doesn't seem to be implemented in GCC 4.1.2 template<typename T> struct X { X(T&) { } }; X<int&> f(int& i) { return X<int&>(i); } <source>: In instantiation of 'X<int&>': <source>:6: instantiated from here <source>:3: error: forming reference to reference type 'int&'
