I briefly had a look and mir.rc.ptr.createRC [1] calls mir.conv.emplace [2], which is a public import of core.lifetime.emplace, which as far as I can see uses typeinfo for that [3]. You also have a custom typeinfo implementation in mir.typeinfo [4], but I didn't see anything regarding initializing the vtbl pointer in there, just about the pointer to the destructor.

Nevermind. Hmm, yes, you are right, it uses typeinfo to initialize the payload :/
