[pkg-ntp-maintainers] Bug#700018: ntpd 4.2.6.p5+dfsg-2 crashes when -I is used to specify the source interface in Debian testing

[Justin Piszcz]

Package: ntp
Version: 4.2.6.p5+dfsg-2

Problem: when -I eth1 (or your_interface_here (which is not part of the
default route)) is specified -- ntpd crashed after about 10 minutes

# cat /etc/default/ntp
NTPD_OPTS='-g'
#NTPD_OPTS='-g -I eth1'


[334743.074156] ntpd[31953]: segfault at 737c ip 000000000040f3f4 sp
00007fffee7ee990 error 4 in ntpd[400000+7c000]

No debugging symbols in this binary however..
