Leaving GHCi. }}} With Test.hs being: {{{ {-# LANGUAGE TemplateHaskell #-} {-# OPTIONS_GHC -fno-omit-interface-pragmas #-} main :: IO () main = return () }}} I want to make TemplateHaskell generated non-essential info visible even with -O0. Compilation works, everything is fine. But I can't load source code like this with GHCi, which is annoying. Setting priority to high, since this is a crash. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8333 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
