Basically StgCse reverts unarise by using case binders when scrutinee is a unboxed tuple
I should add that this is only a bug when we run StgCse after unarise. Before unarise unboxed tuple terms can be replaced by case binders. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15300#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
