title: What types of false positive memory leaks can be reported?
body: <p>When you look for memory leaks using some kind of "tool" like, for example, WinDbg, GlowCode or even the integrated Visual C++ leak reporter, what types of false positives can be reported?</p>
  
  <p>In fact, GlowCode warns you against false positives. Depending on the type of scan that you run, more false positives can appear.</p>
  
  <p>With this question I'm trying to figure out things like how GlowCode scanner compares to WinDbg's <code>!heap -l</code>...</p>
  
  <p>I'll appreciate any hint you can provide!</p>
  
  <p><em>UPDATE:</em> If you could give some <strong>real</strong> example in C++ (or your preferred language) that would help a lot. </p>
