Use of ::_destruct() in arbitrary objects

In digging into a problem with Protocols.HTTP.Promise, I came across an issue with inheritance and destructors.

#ifdef HTTP_PROMISE_DESTRUCT_DEBUG # define PROMISE_DESTRUCTOR \ protected void _destruct() { \ werror("%O()._destruct()\n", object_program(this)); \ } #else # define PROMISE_DESTRUCTOR #endif

Activating this debug flag actually prevents the parent destructors from being called. And simply adding ::_destruct() into there doesn't work either, as that will break for anything that DOESN'T have a _destruct in its parent.

How can this be solved generically? The symbol ::_destruct simply can't be looked up (at compile time) if the parent doesn't have one.
