I am trying to understand haskell program not written by me. During runtime one function is called with parameters which makes the function throw an error. I want to know from where the function is called.

If this is an exception, as opposed to crashing with a signal, then you can compile the program with profiling and pass it parameters "+RTS -xc" to see the evaluation stack when the exception is thrown. See the description of the -xc RTS option at http://www.haskell.org/ghc/docs/latest/html/users_guide/runtime-control.html.... -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
