Jason Rhinelander 1f8a100d38 Track base class pointers of instances ... This commits adds base class pointers of offset base classes (i.e. due to multiple inheritance) to `registered_instances` so that if such a pointer is returned we properly recognize it as an existing instance. Without this, returning a base class pointer will cast to the existing instance if the pointer happens to coincide with the instance pointer, but constructs a new instance (quite possibly with a segfault, if ownership is applied) for unequal base class pointers due to multiple inheritance.		2017-04-27 09:12:41 -04:00
