Do *not* link your shared lib with the Lua library: you'll end up with
two copies and bad things will happen. I cannot tell whether this is the
main glitch, though. Your Lua program is too complicated: you should not
be using package.loadlib directly unless you have good reason, which does
not seem to be the case. Just write a proper Lua library and require it.
