title: Visual Studio debugging execution path
body: <p>I have c code like.</p>
  
  <pre><code>FILE * fin = fopen("myfile", "rb");
  if (fin == NULL)
  {
      printf("file myfile does not exist, closing");
      return false;
  }
  </code></pre>
  
  <p>It works when compiled, but not in debugging mode (stepping trough) where it return false.
  checking argv[0] is ok and absolute paths are working both ways.</p>
