Ah, that's it. The includes really are wrong - if you compile with -Wall you should get the same warnings. It just happens to work on a machine where sizeof(char*) == sizeof(int) - ie. not AMD64. Tested with -m32 and it runs without segfaulting. Nye -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
