When minifying the following function

module.exports = function outer() {
  var myFunction = function myFunction() {                                                                       
      myFunction();
  };
  myFunction();
};

with the following incantation

./node_modules/.bin/uglifyjs --compress '' file.js -o minified.js

Then the following warning will be emitted: WARN: Dropping unused variable myFunction

This is not correct, because the variable is used inside the recursive call. Furthermore, this will generate invalid code that references myFunction inside the function call and you will get an undefined variable error at runtime

We've confirmed that this broke in the most recent build (2.8.8)
