Description

With the current Mesos master state (commit 42e515bc5c175a318e914d34473016feda4db6ff), the Docker executor segfaults during shutdown.

Steps to reproduce:

1) Start master:

$ ./bin/mesos-master.sh --ip=127.0.0.1 --work_dir=/tmp/jp/mesos
WARNING: Logging before InitGoogleLogging() is written to STDERR

(note that building it at 13:37 is not part of the repro)

2) Start agent:

$ ./bin/mesos-slave.sh --containerizers=mesos,docker --master=127.0.0.1:5050 --work_dir=/tmp/jp/mesos

3) Run mesos-execute with the Docker containerizer:

$ ./src/mesos-execute --master=127.0.0.1:5050 --name=testcommand --containerizer=docker --docker_image=debian --command=env

Relevant agent output that shows the executor segfault:
