Hi Sakari,

yes, i am using the binary version of doctest. I don't know
where the extra space comes from, but that is not the problem.

Do you have any idea, what the error message wants to tell
me.  What does "interpreter exited with .." mean. If i add a
main-method i can run the program flawlessly with runghc, but
doctest still refuses to work.

Kind regards
