That looks a further different problem. The `operator new`s (e.g. `_ZdaPv`) is loaded from `libstdc++.dll.a` as `LazyArchiveKind`, which can't be a weak symbol thus weakness of `__real__ZdaPv` can't derive to `_ZdaPv` and `__wrap__ZdaPv`.
(Ah, then, 'inherit weak' might not be needed?)
Anyway, I believe that pulling `__wrap__ZdaPv` feels odd but not a problem.
