I3 4.10.2 has crashed on me. I've seen crashes before but have ignored them. 
I'm interested in seeing if I can isolate the crash, particularly since I think 
I know how to repeat the crash. Once isolated I can provide feedback to the dev 

I am currently presented with the "crash response window" (red border with 
options to: attach gdb, save a backtracke, restart i3 in place, forget the 
current layout and restart i3).

When I putty into the box and see what i3 processes are running (with an eye 
towards attaching gdb), I see the following:

ubuntu@sensis-8930:~$ ps -aef | grep i3
ubuntu    2349  2075  0 Jun17 ?        00:00:01 i3-with-shmlog

--exit-with-session /usr/bin/im-launch i3-with-shmlog

/usr/bin/im-launch i3-with-shmlog
ubuntu    2484     1  0 Jun17 ?        00:00:00 /bin/sh -c i3bar --bar_id=bar-0 
ubuntu    2485  2484  0 Jun17 ?        00:00:29 i3bar --bar_id=bar-0 
ubuntu    2487  2485  0 Jun17 ?        00:00:00 /bin/sh -c i3status
ubuntu    2489  2487  0 Jun17 ?        00:00:24 i3status
ubuntu    2510     1  0 Jun17 ?        00:00:00 /bin/sh -c i3-sensible-terminal
ubuntu    6031  6005  0 12:12 pts/1    00:00:00 grep --color=auto i3

The area that I built i3 out of is:  /home/ubuntu/work/i3/i3-4.10.2

This is where I should be able to find the source code and symbol files 
required by gdb.

I've attached gdb to debuggable processes in the past (I don't need help with 
that). I do need some guidance relative to the following questions:
1] If I save a backtrace, where will that get saved on the system
2] Of the processes listed above, which one do I attach to (I don't see i3.. 
perhaps i3-with-shmlog)?
3] What are the commands that I should enter into gdb so that it loads the 
proper symbol files?

Thanks for any thoughts or guidance.
