        <pre>Hi,

I believe Clang shouldn't compile the code below with -std=c++20.

struct X
{
    int a;
};

int main()
{
    X x{.a = 0, .a = 1};
    return 0;
}

GCC fails to compile it with the error:
error: '.a' designator used multiple times in the same initializer list

   14 |     X x{.a = 0, .a = 1};


Clang trunk successfully compiles the example.</pre>
