[Haskell-cafe] Hint causes GHCi linker error under Windows

The following hint code causes GHCi to crash under Windows:

>  runInterpreter $ loadModules ["SomeModule.hs"]

The error message is: 

GHCi runtime linker: fatal error: I found a duplicate definition for
symbol _hs_gtWord64 whilst processing object file
   C:\Programme\Haskell Platform\2009.2.0.2\ghc-prim-0.1.0.0
HSghc-prim-0.1.0.o
This could be caused by:
   * Loading two different object files which export the same symbol
   * Specifying the same object file twice on the GHCi command line
   * An incorrect `package.conf' entry, causing some object to be
     loaded twice.
GHCi cannot safely continue in this situation.  Exiting now.  Sorry.

The problem does not occur under Unix or with a compiled program. IMHO
hint tries to start a second instance of GHCi which is not
allowed/possible under Windows. If this is the case a more telling error
message would be helpful.

I used the Haskell Platform, version 2009.2.0.2 under Windows XP. My
package.conf is:
