Comment (by tdammers):

 Did some quick testing; `{-# NOINLINE (<+>) #-}` does "fix" the problem
 (bringing compilation time for the example here down from 8 minutes to
 less than one second); however, the patch from
 https://ghc.haskell.org/trac/ghc/ticket/13253#comment:24 doesn't seem to
 make a difference.
