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

[aditya siram]

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.
