If you can run your code through the ghc debugger you can get it to break when an undefined exception is raised. The options are :set -fbreak-on-exception or -fbreak-on-error. More info in the documentation at http://www.haskell.org/ghc/docs/latest/html/users_guide/ghci-debugger.html#ghci-debugger-exceptions Hope that helps, Alex MDC
