Reduced test case:
-------------------- test.d
void main()
{
    S s;
    auto t = s.copy();
    assert(t.count == 1);   // (5)
}
struct S
{
    int count;
    this(this) { ++count; }
    S copy() { return this; }
}
--------------------
% dmd -run test.d
core.exception.AssertError at test(5): Assertion failure
--------------------
