[Vm-beginners] Fwd: Oops - I put a halt in a startup method

[Mariano Martinez Peck]

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!
