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).
