[Haskell-cafe] ghc 7.10.3 crashes frequently on Windows

I have installed ghc from Haskell Platform version 7.10.3. When I run QuickCheck or HSpec tests interactively, every so often ghc crashes when I reload a file form withing Emacs and haskell mode. This problem manifested in earlier versions as well. Loading a file which does not contain tests never crashes ghc so far. How could I try to identify the cause of the crash?
