Hi all! We discovered that one of the kyua test failing from gettimeofday tests. The error is reproducible on recent snapshot from 11-CURRENT: ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/amd64/amd64/ISO-IMAGES/11.0/FreeBSD-11.0-CURRENT-amd64-20150630-r284969-disc1.iso root@freebsd:~ # cat test-gtod.c #include <sys/time.h> #include <stdio.h> int main(int argc, char **argv) { return (gettimeofday((void *)-1, NULL)); } root@freebsd:~ # make test-gtod cc -O2 -pipe test-gtod.c -o test-gtod root@freebsd:~ # uname -a FreeBSD freebsd 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r284969: Tue Jun 30 22:05:35 UTC 2015 root@releng2.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC amd64 root@freebsd:~ # ./test-gtod Segmentation fault (core dumped) root@freebsd:~ # gdb ./test-gtod GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
