DUMP: SIGSEGV: ABORTING! Segmentation fault (core dumped) dump was working fine in -current as of Dec 25. The only changes to it since then are the introduction of <sys/queue.h> instead of a home-rolled list and the replacement of '\007' with '\a'. These changes are innocuous; if backed out, dump still segfaults. This suggests that the problem has been triggered by a kernel change. >How-To-Repeat: $ dump 0af /dev/null / >Fix: None known. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
