Note on item ordering: RPITITs are typically last in this list, so we typically do not encounter RPITITs here (and thus, it's harder to reproduce this ICE).

However, when we have a macro, the identifier of the macro wasn't being adjusted, so although it had the same Symbol, it has a different span and thus identifier equality works a bit differently. So we fall through the assoc item list to the RPITITs, and try to compute their item names and ICE.
