I have master (which should be more or less like latest 5.1) running with app_lua, but on debian 9.0. From backtrace, no obvious issue. Wondering if you can get a stripped down version of you config with as less loaded modules as possible and minimal routing blocks that expose the issue, so I can try it here. Try to load only the app_lua and the modules it binds to and see if crashes ... if not, it could be a side effect from other place.
