According to Joe Talbott: > I've tried this on a RedHat box and a SunOS box both worked as expected. What about changing your expectations then ? The system is reacting as it should as you pointer is pointing to somewhere in the ether and no space has been allocated for it thus a segv. Don't take your "success" on other systems as a proof BTW, it all depends on the implementation of the C startup code and whether the first page (i.e. offset 0x0) is mapped in your process or not. In FreeBSD the first page is unmapped to catch such programming errors. -- Ollivier ROBERT -=- FreeBSD: The Power to Serve! -=- roberto@keltia.freenix.fr FreeBSD keltia.freenix.fr 5.0-CURRENT #80: Sun Jun 4 22:44:19 CEST 2000 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
