Category: Compiler (Parser)
Status: Closed
Resolution: Fixed

Submitted by: chak
Assigned to : nobody
Summary: End of RULES pragma and indentation

Details: The following bug occurs in GHC 4.11, but not in GHC 4.08.1.

Given the module

<code>
module Bug where

{-# RULES

  "foo" foo 1 = 1

#-}

foo 1 = 1
</code>

(where it is essential that #-} starts in column 1), GHC

although the given module should be legal - moreover, the
given line number is wrong.
