This appears to have been due to a lack of manual upgrade testing (we don't
have any automated upgrade testing in place).
The check in {{getExecutorInfo(...)}}
[here|https://github.com/apache/mesos/blob/1.2.0/src/slave/slave.cpp#L4609]
crashes with an old master because it occurs before our injection in
{{run(...)}}. See the {{runTask(...)}} call into {{getExecutorInfo(...)}}
[here|https://github.com/apache/mesos/blob/1.2.0/src/slave/slave.cpp#L1556].
