FYI:

I get the journal by login to tty2,and I'm able to login after a reboot.

After a reboot,I get by running journalctl -p 3 :

Comment 4 Jakub Filak 2016-09-05 10:54:59 UTC
Thank you for the report.

Please, run the following commands and post the output here:

# cd /var/spool/abrt/ccpp-2016-09-05-16:12:30-3002.new
# gdb --batch --ex "t a a bt" -c coredump
# cd /var/spool/abrt/ccpp-2016-09-05-16:03:03-10981
# gdb --batch --ex "t a a bt" -c coredump

Comment 5 lnie 2016-09-06 05:36:15 UTC
It seems that we can't get the output,before #1373355 is fixed,as we can't 
debuginfo-install ccpp successfully.

Comment 6 Jakub Filak 2016-09-06 06:09:12 UTC
(In reply to lnie from comment #5)
Well, if there is no other bug, then the commands from comment #4 should print out backtrace anyway. The output will lack source files, line numbers and local variables but we will see what crashed and where it crashed.
