Comment(by maeder):
Ok, I could observe a problem with a 32bit ghc-7.0.0.20101028 after
installing the MissingH package (via "cabal install MissingH"). It simply
does not return for me and I interrupted it. But running only the Regex
example works after a fresh restart of ghci! Maybe there is a problem with
the many libraries involved.
Can you compile your program without package MissingH (i.e. by replacing
splitWs by words)?
