Reporting as ordered: ghc.exe: panic! (the `impossible' happened, GHC version 6.4)

  I just got this:

---8<-----------------------------
<interactive>: Not x86 PEi386
ghc.exe: panic! (the `impossible' happened, GHC version 6.4):
       loadObj: failed

Please report it as a compiler bug to glasgow-haskell-bugs@xxxxxxxxxxx,
or http://sourceforge.net/projects/ghc/.
---8<-----------------------------

  I've reduced the haskell program down to this:

---8<-----------------------------
import Graphics.Win32
main = allocaMessage (\msg -> return ())
---8<-----------------------------

  Neat, huh?
