title: The function "step into my code" in Pycharm
body: <p>In the debug mode in Pycharm, when I click "step into my code", it doesn't step into the function or next line while it immediately runs all the program left and ends automatically. (under Windows 10)</p>
  
  <p>But the same code in Ubuntu 16.04, it doesn't have the problem, and the "step into my code" works perfectly.
  I've reinstalled the pycharm but couldn't fix this issue. Are there any reason that causes the problem in Windows 10?  Thank you.</p>
