Moreover, if we don't we can get obscure failures in coreToStg; see Note [runRW arg] in CorePrep. This fixes Trac #11291, and makes DfltProb1 compile with -O always in order to expose it more vigorously }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11291#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
