`init is not defined` when transpiled with webpack

I’m trying to transpile my project which has some dependencies that are using debug, and I got an error when I try to transpile it with this webpack config :

{
  target : "node",
  module : {
    rules : [{
      test    : /\.js$/,
      loader  : "babel-loader",
      options : {
        babelrc : false,
        presets : [
          ["@babel/preset-env", {
            "targets": { 
            "node": "6.11.2"
            }
        }]
       ]
      }
    }]
  }
}

The stacktrace is leading me to "./node_modules/debug/src/node.js" with this error "ReferenceError: init is not defined" I’m using node.js v12.13.1, with webpack 4.41.5 and babel 7.

@yvele @gdepouilly Closing for now. Feel free to link back to this issue from the issue you open with Microsoft, for visibility and tracking purposes. 😃

Honestly, it looks like microsoft’s engine doesn’t support function hoisting, which is odd since it’s part of the javascript specification.
