Bug 222728

I'm trying to run a shell script to install docker in FreeBSD on Vagrant, but when I instruct Vagrant to run the script, it reports an ssh command failure. With debugging enabled, Vagrant shows this strange segfault near a chmod section.

Trace:

$ VAGRANT_LOG=debug vagrant provision

went wrong.
