title: Ran Pycharm debug which ended with exit code -1
body: <p>Just a quick question but I ran Pycharm debug on a lengthy series of test scripts and the end result was:  </p>
  
  <pre><code>"Process finished with exit code -1"
  </code></pre>
  
  <p>I was just wondering what this means given that exit code 0 is a pass and exit code 1 is a fail. (is it super awesome code to end in -1?)</p>
