Yeah, it looks like some attention needs to be paid to whether
ate_oldctid and ate_newctid were supplied, rather than just blindly
passing pointers to possibly-uninitialized local structs.

Offhand I think you could remove the "switch" entirely in favor of
driving the setup of these fields off the "if (ItemPointerIsValid(..."
tests.
