Is this form of initialization valid for arrays?

The following code only compiles to clang AFAIK:

struct A { 
  char x[4]; 
  A():x("bug") { } 
};

int main()
{
    char x[4] ("bug");
}

      

        
        
        
      

    

But according to this gcc bug report it is valid code and has been patched for a later version of GCC (someone should report this to Microsoft as well then.)

Rationale for fixing this error:

§ 8.5 / 13

The form of initialization (using parentheses or =) is usually minor, but does matter when an initializer or object is initialized to a class type; See below. If the entity initialized does not have a class type, the list of expressions in the parenthesized Initializer must be a single expression.

The initialization of arrays char

with string literals is covered in § 8.5.2, which shows only an example using the equal sign. Since this kind of initialization is different from other kinds, is this code valid by the standard?
