Here the first (banged) field of SDC gets initialised to a global closure. Clearly it is non-tagged and not evaluated.
That is very wrong. Can you show the `-ddump-simpl -ddump-stg` of the module that allocates an SDC closure with a non-tagged, non-evaluated argument? Thanks. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14626#comment:35 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
