I'm building HEAD, which is at commit 5d04603b33d285565774, though a27b2985511800fa3b740fef82 (HEAD~2) introduced the code in question. This is, I'm pretty sure, literally a one character (and a whitespace, at that) fix. Attached is the patch. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8771 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
