           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

The following program should be well-formed, but is not:

template<class T,
  class =3D decltype(T())
>
char f(int);

template<class>
char (&f(...))[2];

static_assert(sizeof(f<int[]>(0)) !=3D 1, "Error");=20

"cannot value-initialize array of unknown bound =E2=80=98int []=E2=80=99"
