Sean: it may be difficult/impossible. But....you may want to try invoking the function say printOop() from the XCode console.<br>If you read my post:� <a href="http://marianopeck.wordpress.com/2011/04/23/how-to-debug-the-vm/">http://marianopeck.wordpress.com/2011/04/23/how-to-debug-the-vm/</a><br>
<br>Then instead of doing &quot;<code class="plain">(gdb) call printAllStacks()</code>&quot;� you can try something like &quot;<code class="plain">(gdb) call printOop(</code><code class="plain">526237628</code><code class="plain">)</code>&quot;� and that will print something like &quot;an XXX class&quot;.<br>
Of course, you need to replace <code class="plain"></code><code class="plain">526237628</code><code class="plain">� with the real OOP of your receiver object.</code><br><br>Good luck!<br><br><div class="gmail_quote">On Fri, Sep 9, 2011 at 5:35 AM, Sean P.
