Summary: ghc --make panic on fptools/ghc/compiler/Lexer.hs

Initial Comment:
I am trying to use ghc's lexer in my own project. When
building module that imports Lexer module I am getting
this error:

ghc-6.4: panic! (the `impossible' happened, GHC version
6.4):
        expectJust upsweep_mod:old_linkable


My reproduction project(attached) consists of two files:

Main.hs
========>
module Main where



import Lexer



main = putStrLn "hello"
<=========
and Makefile.

You may have to edit Makefile to provide the correct
path to the fptools folder. Running make demonstrates
the error.

I am using ghc-6.4 on gentoo.

Thank you,
