The Lua runtime that ships with OpenWrt is broken. It is broken by
one (or more) of the patches.<br>
<br>
I have create a ticket a while back about this issue, which you can
find here: <a class="moz-txt-link-freetext"
href="https://dev.openwrt.org/ticket/20821">https://dev.openwrt.org/ticket/20821</a><br>
<br>
I was able to work around this issue removing/fixing patches and
compiling my own version of the Lua package.<br>
<br>
However, just today, I hit this issue AGAIN using a busybox docker
container (which uses OpenWrt x86 packages).<br>
<br>
Ubuntu docker container. Everything works fine.<br>
<br>
<small> $ docker run -it --rm ubuntu:14.04
