No return on Windows and Node v7.1.0?

The script below comes to a complete and silent stop at line 28 specifically under node v7.1.0 in Windows. No error, no exception, no stack dump, just a silent drop out to the command line as if nothing devastatingly horrible had just been perpetrated. 😃

If I backtrack the node version to v7.0.0 or earlier, it works. Same script also works as expected on a Mac, in v7.1.0.

The console.log(res) on line 27 does execute, but the return seems to never happen properly; line 31-32 with console.log('\n\nvoteds', voteds); never shows an array built from map() on line 17. Also, the catch() and finally() never execute.

Any suggestions?

/* jslint node:true, esversion:6 */
'use strict';

const _        = require('lodash');
const promise  = require('bluebird');

const fs       = promise.promisifyAll(require('fs'));
const rp       = require('request-promise');

fs.readFileAsync('emails.txt', 'utf8')
  .then(function(file) { // read file into an array
    //console.log('file', file);
    return promise.map(file.split('\r\n'), line => {
      return { Agent: null, VoterID: null, Email: line, IsVerified: null };
    });
  })
  .map(function(email) {
      //console.log('email', email);
      let options = {
          uri: '...',
          method: 'POST',
          body: { email: email.Email },
          json: true 
      };
      return rp(options)
        .then(function(res) { 
          console.log(res); 
          return res;
        });
  })
  .then(function(voteds) {
    console.log('\n\nvoteds', voteds);
  })
  .catch(function(err) {
    console.error('\n\nERROR', err);
  })
  .finally(function() { 
    console.log('\n\ndone!'); 
  });

I’m exploring https://github.com/nodejs/node/issues/9542 as a possible reason, with help from a Gitter user(@not-an-aardvark on petkaantonov/bluebird) given the specificity of the error wrt to the node version and environment, there must be a regression or a bug introduced.

Thanks, good to know!
