Simon, I (stupidly) called the executable logger and then presumably invoked something on linux of the same name. Giving it a different name gave the same result as you got. I assume this is a bug in hugs and I will refer it to that mailing list. Dominic. simonmar@microsoft.com on 25/05/2001 13:03:00 To: Dominic Steinitz haskell cc: bcc: Subject: RE: IO Errors

In ghc, the program hangs without even creating a file.

With GHC 5.00.1 here it creates the output file containing: Starting logging 1234567812345678 Finishing logging which GHC version was hanging for you?
