if you see such a message, the first thing you should do is to analyze the problem with Valgrind - just install it and prepend the command you start your program with (including command line arguments) with "valgrind ", and look at the first error message. One possible cause of such an error would be that your function "f" writes to memory that you don't own. Cheers, Frank
