I have an app that is crashing with no error tracing. I can see part of what is going on if I debug, but can\'t figure out which object is \"zombie-ing\".
In XCode 4.0: To detect NSZombie in Instruments, select the Simulator as your target (can't detect NSZomboe on device). Run Instruments (CMD+I) and select "Zombies" trace template. Enjoy.
