Comment (by scpmw):

 Interesting. I checked, and the code I used to reproduce the problem was
 exactly what simonpj suggested, but with an extra SCC on the `doCorePass`
 call. That way, I could catch exactly the "leaking" costs. Maybe that
 annotation also changed the compiler behaviour sufficiently to stop this
 from working.

 Anyway, all the better. Maybe we should close this ticket then, and
 continue the discussion of the larger issue in #5654?
