5086	internal error: update_fwd: unknown/strange object  -1206004376	danw	simonmar	"When I compile my parallel program with the following command line:

ghc -O2 --make -threaded Main.hs

Then run the program with the following command:

./keno +RTS -N -M8G

The program crashes with the following error:
keno: internal error: update_fwd: unknown/strange object  -1206004376                        
    (GHC version 6.12.3 for x86_64_unknown_linux)                                            
    Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
