<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>
