Comment (by simonpj):

 Replying to [comment:5 wyager]:
 >  why is the specializing behavior different than it was in the previous
 Haskell-platform's GHC? Did it start to specialize less aggressively?

 I'm afraid I don't know -- and I am reluctant to invest the time in
 finding out.  But that shouldn't stand in the way of someone else looking.
