import core.atomic;
import core.stdc.stdio;
struct S
{
    int i;

    this(int i)
    {
        this.i = i;
        puts("c");
    }

    this(this)
    {
        puts("p");
    }

    ~this()
    {
        puts("d");
    }

    this(int r, int e)
    {
        this = sum(r, e);
    }

    static S sum(int r, int e)
    {
        return S(r + e);

void main()

    auto c = S(1, 2);
}
