--- Comment #1 from kinke <kinke@gmx.net> ---
This seems caused by `scope` allocations for (D) classes getting an implicit `delete stackConstD`, while C++ classes don't. Which is probably a bug in its own right.

The `delete` expression is deprecated; it resets the pointer to null, that's why it cannot be const. An updated lowering could use `destroy()` instead (it's only about calling the dtor/finalizer AFAICT), for C++ classes too, which should make it work with const as well (without dtor or with a const dtor).

Good catch! I filed a separate bug for that:

Yes, that is how it should work.
