这个代码给我一个编译错误在Clang：

struct A
{
   A(int first,int second) {}
};
void myFunc()
{
   new A[1] {{1,2}};
}

我预计{{1,2}}用单个元素初始化数组,然后使用构造函数args {1,2}进行初始化,但是我收到此错误：

error: no matching constructor for initialization of 'A'
   new A[1] {{1,2}};
            ^
note: candidate constructor not viable: requires 2 arguments,but 0 were provided
   A(int first,int second) {}
   ^
note: candidate constructor (the implicit copy constructor) not viable: requires 1 argument,but 0 were provided
struct A
       ^

为什么这个语法不起作用？
