breaks bundling

[ghost]

Hello,

// webpack.config.js
const path = require("path");
const MinifyPlugin = require("babel-minify-webpack-plugin");

module.exports = {
  devtool: "source-map",
  entry: "./src/index.js",
  output: {
    path: path.join(__dirname, "artifact"),
    filename: "bundle.js"
  },
  module: {
    rules: [
      {
        enforce: "pre",
        test: /\.js$/,
        exclude: /node_modules/,
        loader: "eslint-loader"
      },
      {
        test: /\.js$/,
        exclude: /node_modules/,
        loader: "babel-loader"
      }
    ]
  },
  plugins: [new MinifyPlugin()]
};

leads to

$ webpack
/home/le93us/Desktop/php-study/node_modules/webpack-sources/node_modules/source-map/lib/source-map-generator.js:276
        throw new Error(
        ^

Error: original.line and original.column are not numbers -- you probably meant to omit the original mapping entirely and only map the generated position. If so, pass null for the original mapping instead of an object with empty or null values.

If disable plugin, all works ok.

Can someone help?

@le93us Thanks for issue. Duplicate #68, can you create minimum reproducible test repo and put in issue #68?
