Wackamole dumps core when peer is added or removed from group, if not currently assigned to virtual ip address and hostname assigned 127.0.1.1 in /etc/hosts

[Eric Williams]

Binary package hint: wackamole

## Issue

* wackamole Aborts with "Assertion `ret == My.num_allocated' failed." when IP address requires failover

* Wackamole dumps core when peer is added or removed from group, if not currently assigned to virtual ip address

* wackamole daemon exits if not currently assigned to virtual ip address and another peer enters or exits the group

## Environment

* Lucid 10.04.2

* wackamole 2.1.1-3.1

* hostname defined as "127.0.1.1" in /etc/hosts (default)

## Resolution

* (workaround) remove the 127.0.1.1 from /etc/hosts from all machines in the group, and it seems to work

## Diagnostic Steps

* install and configure wackamole

* create virtual ip group with multiple hosts

* start wackamole with:

  wackamole -c /etc/wackamole.conf -d

* shutdown wackamole on machine that currently has IP address assigned

* remaining wackamole daemon aborts with the following error:

wackamole: wackamole.c:702: Send_state_message: Assertion `ret == My.num_allocated' failed.
Aborted (core dumped)
