--- Comment #1 from moonlightsenti...@disroot.org ---
Modified:

extern (C) int printf(scope const char*, ...);

struct S
{
        this(int arg)
        {
                a = arg;
                printf("this(%d), this = %p\n", a, &this);
        }

    ~this()
    {
        printf("~this(%d), this = %p\n", a, &this);
    }

        int a;
}

void main()
{
        auto s = true ? S(1) : S(0);
    printf("main\n");
}

----

this(1), this = 0x7fff3b745b88
~this(1), this = 0x7fff3b745b88
main
~this(1), this = 0x7fff3b745b98

So there's only one dtor call for the temporary created inside of the ternary
operator and another call for the variable s at the end of main.
