this bug was fixed at Nov 15 so you should just donwload up-to-date GHC
snapshot:

  * MERGE: Fix (yet another) odd interaction between selector thunks and compacting GC

    * Fix (yet another) odd interaction between selector thunks and compacting GC
    This should fix errors of the form
    
      internal error: scavenge_mark_stack: unimplemented/strange closure
        type 28 @ 0x2b92e5f79960
    
    But since it's quite difficult to reproduce the error, I can't be 100%
    certain it's gone.  I certainly can't reproduce it again after the
    fix, anyway.

    M ./rts/GC.c +8
