There are many things i do not understand. Why the different behaviour on Linux and Windows? Shouldn't an exception be thrown on Linux instead of a core dump? I don't use any unsafePerformIO or foreign calls. Why the changed path? I never change working directory in my code. Why is a function (-> reading the config file) re-evaluated at a later point in time?

How can I debug such a problem?

My environement is ghc 6.6 on Ubuntu or Windows XP.

It may be difficult to say without seeing your code. Is it possible for you to post it, or at least a minimal test case that would illustrate the different errors on the different OSes? What Unix toolkit are you using when running ghc on Windows, if any (cygwin, mingw, both, neither?)

I know that it's difficult without code but unfortunately the whole program is already quite large (several thousand lines) and I wouldn't see how to extract a relevant test case at the moment as i have no real clue where to search for the problem. I use cygwin on Windows. I just compiled the application from a cmd.exe and the result is the same (even though cmd.exe (and the normal cygwin terminal) swallows the error message, but the error is shown when run in rxvt). regards Stefan
