Note that we have zero context pointer in such postblit call:

---
int i;
struct S
{ this(this) { ++i; } }

void main()
{
    S s = S.init;
    assert(i == 0); // postblit not called
    s = S.init;
    assert(i == 0); // postblit not called

    int k;
    static int j = 0;
    struct N
    {
        this(this)
        {
            ++j;
            assert(this.tupleof[$-1] != null); // fails
        }
        void f() { ++k; }
    }

    N n = N.init;
    assert(j == 0); // fails, j = 1, postblit called
    n = N.init;
    assert(j == 0); // fails, j = 2, postblit called
}

This is a derived issue from the bug 9035. If it is correctly fixed, this bug
will be disappeared.
