--- Comment #2 from Matthew Iselin <matthew at theiselins dot net> --- Where would I start in identifying what about the target is causing the issue? The best I can come up with is an issue with the vtable prefix and/or the math to determine the deepest object, but can't (yet) see how the target would affect that.
