ghc.exe: internal error: update_fwd: unknown/strange object  0
     Please report this as a bug to glasgow-haskell-bugs@xxxxxxxxxxx,
     or http://www.sourceforge.net/projects/ghc/

 This occurred using ghc 6.4.1 on a Windows XP system,
 when running the following command:

 ghc -i. -i./ghc -i./win32 -package concurrent -package net -package parsec
 -pack
 age QuickCheck -O2 -Wall -package-name galois +RTS -M500M -RTS
 -Iwin32/include
 -Iinclude   -c Data/Symbolic.hs -o Data/Symbolic.o

 The error is repeatable.
 Unfortunately I can't publish the source files that I'm trying to compile,
 but I may be able to give someone a copy if they are willing to have a
 look
 at the problem.  (This is revision 10447 of trunk/lib/galois in the
 [private]
 Galois SVN repository.)
