There was a real bug, involving accidental name capture in the worker/wrapper pass. It only occurred under very obscure circumstances, which is why it's so hard to reproduce. Patch coming. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12562#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
