[OpenWrt-Devel] Lua patches break runtime

Wed Jul 27 22:17:26 EDT 2016

The Lua runtime that ships with OpenWrt is broken.  It is broken by one
(or more) of the patches.

I have create a ticket a while back about this issue, which you can find
here: https://dev.openwrt.org/ticket/20821

I was able to work around this issue removing/fixing patches and
compiling my own version of the Lua package.

However, just today, I hit this issue AGAIN using a busybox docker
container (which uses OpenWrt x86 packages).

Ubuntu docker container.  Everything works fine.

$ docker run -it --rm ubuntu:14.04

It would be nice if somebody finally fixes this issue or removes the
breaking patches.
