Do we not need to wrap this and `CreateExceptionWithMessage` inside a `__FINALLY_CTX` to clean up any partial allocations in case of an exception being thrown? For instance, `CreateExcception(S_OK)` throws an `InvalidArgumentException` from the constructor, wouldn't that leak the allocation from `AllocateExceptionWithWeakRef`?
