consider the following code

int x;
using intref = int&;
intref w{x}; // A
intref{x}; // B

now, line A compiles correctly both in clang and gcc ( it didn't as of
c++11, defect fixed in c++14 AFAIK )

the problem is line B: clang treats it the way one would expect
( a temporary reference is bound to x ) whereas gcc 4.9 treat it in
the old defected way ( a temporary of type int is created and bound to
the reference, resulting in a compiler error ).

Who's right here ? thank you
