[Haskell-cafe] How to locate a <<loop>>?

Hi. I have a generated Haskell program that emits a "Fail: <<loop>>" at runtime. Are there some tools or standard manner for identifying the lines that participate in the loop? The use of "-debug" and "-prof -auto-all" only provides a call stack, and the loop is, is I understand it, due to a circular definition, so the call stack is of little help. -- Sincerely | Homepage: Jørgen | http://www.hex.no/jhf | Public GPG key: | http://www.hex.no/jhf/key.txt
