ranonymize segfaults when doing specific host translations

[Brad]

Argus devs,

We are using argus-clients-3.0.8 (current stable) on Centos 6.6 (Final
x86_64). We built argus-clients with the default configuration:

    ./configure
    make
    make install

In this environment, ranonymize segfaults when doing specific host to host
translations. Here is the line in the ranonymize conf file (which when
used) causes the segfault:

    RANON_SPECIFY_HOST_TRANSLATION=128.173.1.1::192.168.1.1

We've tried this line both ways original_ip::anon_ip and
anon_ip::original_ip. Unless we missed it, the documentation is not clear
on what side is the original_ip and what side is the anon_ip. We've also
tried using different RFC 1918 addys as the anon_ip. In all cases, the
segfault occurs.

We touched .devel and then re-built the clients. Here is the line number
where the segfault occurs.

Please let us know if we can do anything to test this further.
