LUA Bug?
From: Michael Pattrick <mpattrick () rhinovirus org>

Hello devs,

While playing around with a recent Nmap release I found that scripts
weren't working for me, see the following command line log. It appears
to be a problem with the LUA environment variables. The environment is
a nearly fresh CentOS5 install. I haven't tested this out on other
platforms but a quick google search reveals at least one other person
has had problems with this bug (http://pastebin.com/cFXre59L). Any
ideas?

$ nmap -d9 -A 127.0.0.1
