The lldb I'm using is from XCode 7.0.1.

I can debug my binary if I run lldb as root.

I eventually figured out my actual bug from log messages without lldb.  Turns 
out, Mac OS X 10.11 El Capitan doesn't allow the root user to deploy binaries 
to /usr/bin which our installer does so that our binary is in the default ssh 
environment path.  I setup a custom ~/.ssh/environment and configured 
PermitUserEnvironment to yes in /etc/sshd_config and that let my binary run 
normally.

But, still, I can't seem to run lldb as a normal system user with our binary.
