Unexpected output with webpack2

[hydra1983]

The code below will assign the created RegExp to options.search, in webpack2, the options.search will be reused for next file processing. So, the RegExp will be another one other than the first one expected.

function processOptions(source, options) {
  if (!_.isUndefined(options.search) && !_.isUndefined(options.replace)) {
    if (!_.isUndefined(options.flags)) {
      options.search = new RegExp(options.search, options.flags);
    }

    var newSource = source.replace(options.search, options.replace);
    if (options.strict && (newSource === source)) {
      throw new Error('Cannot replace ' + options.search + ' → ' + options.replace);
    }
  } else if (options.strict) {
    throw new Error('Cannot replace: undefined search or/and option(s) → ' + JSON.stringify(options));
  }

  return newSource;
}
