-------------------------+--------------------------------------------------
I've been playing around with the ICFP "universal machine" puzzle
 (http://icfpcontest.org/task.shtml)
 For prototyping, I'm using runhaskell as a "script engine" from the SciTE
 editor on Win32.  I'm running Windows XP Home 2002 SP2 with the package
 GHC6.6 downloaded from haskell.org.

 I have some leftover .o/.hi files from compiling a previous version the
 project via the command line.  If I delete those, the problem goes away.

 I'll attach a zip of the directory contents as a repro case if the bug
 tracker allows me to.
