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 "<code class="plain">(gdb) call printAllStacks()</code>" you can try something like "<code class="plain">(gdb) call printOop(</code><code class="plain">526237628</code><code class="plain">)</code>" and that will print something like "an XXX class".<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.

<div class="im"> My image appears for an instant and then crashes. Is there any way to<br>
recover from this?<br>
<br>
</div>I made some progress, but I'm not sure I'm on the right track...<br>
I built a debug VM and found primitivePerform, which is apparently called<br>
by the following:<br>
<div class="im"> FeaturesDB perform: #startUp: with: resuming<br>
<br>
How will I know which call to skip/break on? Maybe there is there a way,<br>
</div>from the VM side, to get the receiver class name as a string? If I knew that<br>
<div class="im">the receiver was FeaturesDB, that would be the one...<br>
<br>
</div>And then once I have the right call, can I just skip over it?<br>
