A fix is to avoid using a pattern signature in Control/Monad/CatchIO.hs: -onException a onEx = a `catch` (\(e::E.SomeException) -> onEx >> throw e) +onException a onEx = a `catch` \e -> onEx >> throw (e :: E.SomeException) I reported this to the MonadCatchIO-mtl maintainer a few days ago; hopefully it will be fixed soon. (I’ve CCed him as a reminder.) Meanwhile, you can use cgi-3001.1.7.3, which does not require MonadCatchIO-mtl.
