Comment(by j.waldmann):

 I have that same behaviour for 7.0.3

 internal error: update_fwd: unknown/strange object  8
     (GHC version 7.0.3 for x86_64_unknown_linux)
     Please report this as a GHC bug:
 http://www.haskell.org/ghc/reportabug
 Aborted

 when I run the attached program on
 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64
 (should take < 60 seconds, eats up all the heap, then crashes reliable)

 the program does nothing special - just allocate Cons cells.
