 Squeaky boards and rust traps never have a corpse because they are non-lethal. Pits and holes also never generate a corpse - any corpses found in pits are usually from generated monsters that fell in, especially if their associated items are present (e.g. finding an [[orcish helm]] with a [[goblin]] corpse). Magic traps do not have corpses either as a result of not being specified in the relevant code.
