I was using a slightly older build from https://launchpad.net/~hvr/+archive/ubuntu/ghc which included 5f349fe24066e7b0af85934664e27636d2e84fe5, but not f8c8de8ebf73cd77faa0249d92f280e33a8d2624. I can verify that that commit fixes the above issue. Apologies for the noise. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12925#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
