GHC 6.4.1 crash on Windows XP

[Cyril Schmidt]

A freshly installed GHC 6.4.1 on my colleague's PC crashes when I try
to build a package:

runhaskell Setup.hs build

The effect is easily reproduceable (it shows up on *any* package
that I try to build).

Does anyone have any idea of what might be wrong here?

For the record, the information given by Windows at the point of crash:

(The IP and SP already point somewhere inside Dr. Watson, as far
as I can see, so I don't think the registers and stack contents
are of any use at this point.)
