Hi!

We are using sssd 1.13.4 but sometimes get a similar error:

in sssd.log

(Wed May  9 08:23:48 2018) [sssd] [talloc_log_fn] (0x0010): talloc: access after free error - first free may be at (null)

(Wed May  9 08:23:48 2018) [sssd] [talloc_log_fn] (0x0010): Bad talloc magic value - access after free

In syslog:

May  9 08:24:46 SDTPC302 sssd[pac]: Shutting down
May  9 08:24:46 SDTPC302 systemd[1]: sssd.service: Main process exited, code=dumped, status=6/ABRT

May I help to diagnose this? (Users can not login and they need to restart their workstations)
