After a sys upgrade, cronie segfaults with this logs:

Aug 23 14:45:01 lnode crond[6412]: PAM unable to dlopen(/usr/lib/security/ /usr/lib/ symbol __call_tls_dtors, version GLIBC_PRIVATE not defined in file with link time reference
Aug 23 14:45:01 lnode crond[6412]: PAM adding faulty module: /usr/lib/security/
Aug 23 14:45:01 lnode kernel: crond[6412]: segfault at 58f6 ip 00000000000058f6 sp 00007fff387029c8 error 14 in crond (deleted)[400000+c000]
Aug 23 14:45:01 lnode systemd-coredump[6413]: Process 6412 (crond) dumped core.

I guess it's cause by upgrade of glibc (2.17-6 -> 2.18-2)

Additional info:

The system only enabled these repo:


A few packages from AUR:

# pacman -Qm
geoip-citydata 20130311-1
gsutil 20110825-1
obfsproxy-git 20121205-1
openvpn-obfs 2.3.2-4
package-query 1.2-2
xapian-core-stable-with-cjk 1.2.6-1
xapian-python-bindings-stable 1.2.6-1
yaourt 1.3-1

Steps to reproduce:

pacman -Syu
journalctl -e
This task depends upon

Reason for closing:  Not a bug
Additional comments about closing:  This happens every glibc update

Did you restart cronie after upgrading glibc? This looks like mixing symbols from two versions of glibc.

No ... it didn't occur to me that a restart is needed.. my bad.
