title: gdb breakpoint on pthread_create
body: <p>I am trying to set a breakpoint in linux in gdb for a program creating threads.  I would like to set a breakpoint on thread creation, but unfortunately <code>pthread_create</code> is a versioned symbol, and I can't get its full name.</p>
  
  <p>If I type:</p>
  
  <pre><code>catch thread_start
  </code></pre>
  
  <p>I get</p>
  
  <pre><code>Catch of thread_start not yet implemented
  </code></pre>
  
  <p>How is the best way to catch thread creation in gdb for this situation?</p>
