Yes, it fails for every directory. I actually noticed the problem by
when using Cabal, which uses getDirectoryContents. But, I did some
more testing. This works:

    > ghc --make Main.lhs -o main
    > main
    passed

But, this fails:

    > ghci Main.lhs
    Prelude Main> main
        *** Exception: C:\temp\bugs\getDirectoryContents:
getDirectoryContents: failed (
No error)

and this fails:

    > runghc Main.lhs
    *** Exception: C:\temp\bugs\getDirectoryContents:
getDirectoryContents: failed (
No error)    

This indicates to me that there is not any problem with my filesystem.
Instead, it seems like it is likely a problem with the linker. Now, I
see what the cause of the problem is:
