Comment (by simonpj):

 I agree.  Potentially this a serious warning. Someone should look into it!
 It happens if

 * The info about CAF-hood predicted by `CorePrep` differ from...
 * the info about CAF-hood discovered by `CoreToStg`

 I can advise.

 As a systematic fix, I really want to get info about arity and CAF-hood
 from the `CoreToStg` pass, and NOT predict it in `CorePrep`.
