Just limit enviroment ( sandbox ).
Or if you dont want users breaking your app, initialize new lua state/enviroment.

If you are getting a stack overflow you are overriding incorrectly or causing a loop. Make sure that if you are re-calling an override that you use the original call and not your new override. For example:

Code:

local orig_print = print;

print = function(str)
    -- Make sure to call orig_print here instead of you want to still print!
    orig_print('[Override] ' .. tostring(str));
end

print('hello world');
