Comment (by bgamari):

 Good sleuthing!

 However, I'm not sure about marking `absentError` as non-CAFFY. Afterall,
 judging by its RHS it looks as though it may carry a reference to at least
 one CAF (namely `unpackCString# "Oops!  Entered absent arg"#). Have you
 looked at the STG that is produced for this?
