Hi,

we have developed a 'buggy' version of the nofib collection of Haskell
programs. All programs contain one of these bugs:
- a bug that produces an incorrect result
- a bug that produces non-termination
- a bug that produces an exception (e.g., div by zero)

Our buggy nofib suite can be used to test debugging tools. 
It is publicly available as a DARCS repo at
http://einstein.dsic.upv.es/darcs/nofib

There is also a web interface with basic search facilities at
http://einstein.dsic.upv.es/nofib

Any suggestion or comment is welcome!

Best regards,
