 I ran a very memory consuming program on a 32GB machine
 with the following RTS arguments:

 -H18000M -S -c

 hoping that I could avoid all the copying.
 However, I got the following message:

 internal error: update_fwd: unknown/strange object  27330425
     (GHC version 7.0.3 for x86_64_unknown_linux)
     Please report this as a GHC bug:
 http://www.haskell.org/ghc/reportabug
 Abort

 As a side note: with just the -c option, I had run into
 a Segmentation Fault.

 Without any run-time options, the programs fails to complete
 succesfully before running out of memory.
