Bug 1259036

Description of problem:

I was able to get my terminal to spit out a double free or corruption message. This is the last text from the screen:

<<<<<<<<<<<<
[dustymabe@media f22pandoc]$ ##systemctl start etcd.service kube-apiserver.service kube-controller-manager.service kubelet kube-proxy kube-scheduler 
*** Error in `bash': double free or corruption (out): 0x000055fa1df1f7d0 ***
>>>>>>>>>>>>

I'm not sure how I got this to happen but I do know I had recently hit the "home" key and added a new '#' to the beginning of the line. You can see two '#' characters on the line above.


I was able to attach to the process with gdb and I got this out:
