Yeah BUT in my case I wanted to log an error via my own utility and then
call `error()` to get stack trace output and terminate the program. Some
parts of my code look like this:

    if somethingWrong then
         myLogger:log(Level.Error, extraData, "this isn't looking good!")

         error() -- hope to also get stack trace without extra calls

    end

But I'm probably making up a problem for myself...




What Dirk told you seems exactly what you're looking for. Just replace:

error()


with:


error ""
in that code and you'll get an unconditional error with a stack trace, tracing back to the point where you put that call.
If you, OTOH, need a custom error function producing a somewhat customized stack trace, you should build on debug.traceback.
