title: Is it possible to use the terminal malloc_history when debugging on a iPhone device?
body: <p>I've found malloc_history useful when testing on the iOS simulator, is it possible to configure it for a physical device (iPhone 4).</p>
  
  <p>On the <strong>console</strong> I do get similar messages to this</p>
  
  <pre><code>warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.2.1 (8C148)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib (file not found).
  </code></pre>
  
  <p>Do I need to setup this file somewhere?  </p>
  
  <p>On the <strong>terminal</strong> I get this</p>
  
  <pre><code>malloc_history cannot examine process xxxx because the process does not exist.
  </code></pre>
  
  <p>Any direct advice / pointers to documentation would be greatly appreciated.</p>
  
  <p>Thanks</p>
