I want to profile my Haskell program (it solves the Queens and Knights problem stated here: http://www.itasoftware.com/careers/programmers.php ). I'm compiling with GHC 5.04.1 under Windows NT using the following command line (as per the Users Guide):

...

ghc -prof -auto-all -o queens --make Main

When I run the program with the following command lines I get:

...

queens queens: fatal error: evacuate: strange closure type 1696

Profiling is broken on Windows in 5.04.1. I think we know what the problem is, and it will be working again in 5.04.2. Sorry about that. Cheers, Simon
