ghc.exe: internal error: update_fwd: unknown/strange object 0

Please report this as a bug to glasgow-haskell-bugs@…, or

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.)
