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].
