Comment (by bgamari):

 Here I compare what the simplifier does to a term of type `"event_type"
 :-> Int` from my test program in GHC 7.10.1 and 7.10.2.

 The test program (found here
 https://github.com/bgamari/ghc-T10527/blob/master/Bug2.hs) is cut down
 just enough so that it fails with 7.10.2 and succeeds with 7.10.1 with a
 sufficiently low `simpl-tick-factor` (10).
