title: snprintf() , overflow possibility?
body: <p>I have fixed size arrays - arr1 and arr2.    </p>
  
  <pre><code>char arr1[100];
  char arr2[100];
  snprintf(arr2, sizeof(arr2), "%sAND", "CONTENTOFARRAY2");
  snprintf(arr1, sizeof(arr1), "%sAND", arr2);
  </code></pre>
  
  <p>Will the second snprintf , cause a buffer overflow ? I have tried some testing and no issues were noticed so far. </p>
  
  <p>Has anyone noticed any such issues?</p>
