Comment # 7 on bug 908782 from Fulvio Malfatto

For info: What to do to enable coredumps in opensuse 13.1 under systemd

#echo "|/usr/lib/systemd/systemd-coredump %p %u %g %s %t %e" >
/proc/sys/kernel/core_pattern


create /etc/sysctl.d/50-coredump.conf  with this content:
kernel.core_pattern=|@rootlibexecdir@/systemd-coredump %p %u %g %s %t %e


#sysctl -w fs.suid_dumpable=2

after you have the dump in your journal, you can see it with:

# /usr/bin/systemd-coredumpctl list

But I cannot go further, no more info available. 
As usual systemd is born to give us troubles
