template specialization for static data member

Following code can be compiled with MSVC 14.1 but not with Clang 5.0.1.

template <typename T>
class C
{
public:
    static int a[];
};
int C<int>::a[1] = { 1 };

Clang's error message is:

error: template specialization requires 'template<>'

Is this code compliant with C++ standard? I found related passage in here as follows.

When defining a member of an explicitly specialized class template outside the body of the class, the syntax template <> is not used

This isn't an explicitly specialized class template (that would be if you had for example a fully-specialized C<Foo>) so that passage doesn't apply to your code here. You do in fact need template<> for this.
