title: How to analyze core dump
body: <p>After application[rtorrent] crashed, it produced <code>core</code> file, 250MB. </p>
  
  <pre><code>Caught Segmentation fault, dumping stack:B] [Port: 58940][U 0/0] [D 0/10] [H 1/32] [S 72/75/768] [F 0/128]
  Stack dump not enabled.
  Aborted (core dumped)
  </code></pre>
  
  <p>What I need is to analyze and see the stack trace, to have clue why rtorrent is crashing so often.</p>
