title: Shared memory and strings: managed?
body: <p>I have a problem with <code>boost::interprocess::string</code> in shared memory.  </p>
  
  <p>When I use a <code>shared_memory_object</code> I can manipulate a structure with different fields, BUT strings (I get a segmentation fault).<br>
  On the other side, when I use <code>managed_shared_memory</code> everything is fine.  </p>
  
  <p>Am I doing something wrong? Do you know if there is a performance penalty using <code>managed_shared_memory</code>?  </p>
  
  <p>Thank you!</p>
