title: Why am I getting the message "Single-stepping until exit . . . which has no line number information" in GDB?
body: <p>I've compiled my C program using <strong>gcc 4.4.1</strong> using the flag <code>-g</code>, but when I try to step through one of my functions in <strong>gdb version 7.0</strong>, I get the message: </p>
  
  <pre><code>"Single stepping until exit from function _DictionaryTree_getNodeList, 
  which has no line number information."
  </code></pre>
  
  <p>Can someone tell me why this is happening?</p>
