[Haskell-cafe] Reproducible Bug in Emacs' haskell-mode

Hi all, I have a reproducible bug in Emacs' Haskell mode where Emacs gets stuck in an endless loop. I am using GNU Emacs 23.0.93.1. To reproduce: 1. Use a bad Language pragma eg. {-# LANGUAGE FlexibleTypes #-} 2. Load a GHCI instance with C-c C-l. GHCI outputs the following error: unsupported extension: FlexibleTypes 3. Fix the pragma: {-# FlexibleInstances -#} 4. Try to load the file again with C-c C-l and Emacs gets stuck. -deech
