      1. Start a replica set using Mongo 2.2.x.
      2. Populate it with data.
      3. Use mongodump --host <replSet>/<replSetMember:port>

      This behavior works without crashing using Mongo 2.0.x.

      User noticed that specifying --host <replSet>/<memberOfReplSet>:<memberOfReplSetPort> will cause mongodump and anything that uses the destructor of the ReplicaSetMonitor class to crash w/ the stack trace:
