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

[Ivan Lazar Miljenovic]

Try the following:

1) M-x toggle-debug-on-quit (so that it's enabled)

2) Follow your instructions below

3) When it's stuck, do C-g to stop it trying to load the file.

Just so you know, there's also a dedicated mailing list for the Haskell
mode in Emacs; see here for more information:

> 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.
