>Description:
        vtund (vtun-3.0.2nb1) trips over a SIGSEGV when doing lzo operations on 
amd64.
        The SIGSEGV is cause by an inappropriate type for the length argument.
>How-To-Repeat:
        attempt to set up a vtund tummel with LZO compression on amd64.
        SIGSEGV happen after the tunnel is set up.
>Fix:
Additional patch (patch-lfd__lzo.c) for vtun-3.0.2nb1:
