Hi,
I'm sorry to bother. I was using the splitRegex function
http://cvs.haskell.org/Hugs/pages/libraries/base/Text-Regex.html#t%3ARegex
and it enters an infinite loop when I enter the command
(splitRegex (mkRegex "") "hi")
I apologize if this is not a bug or if it's the wrong place to submit it.
Best regards,
damian.
