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

From http://forum.world.st/Oops-I-put-a-halt-in-a-startup-method-td3800163.html: My image appears for an instant and then crashes. Is there any way to recover from this?

I made some progress, but I'm not sure I'm on the right track... I built a debug VM and found primitivePerform, which is apparently called by the following: FeaturesDB perform: #startUp: with: resuming

How will I know which call to skip/break on? Maybe there is there a way, from the VM side, to get the receiver class name as a string? If I knew that the receiver was FeaturesDB, that would be the one...

And then once I have the right call, can I just skip over it?
