I've done a clean build, made sure ZeroLink is off, and turned off
all stripping. I'm not doing any remote debugging, which is the only
thing the archives turns up. This is a simple 10.4 universal binary.
You can't set NSZombieEnabled after a program has started running.
You need to set it as an environment variable and restart your app.
You can do this from Xcode's executable inspector's environment
variables tab.
Or you can do it in gdb:
set env NSZombieEnabled=1
run
You might also want to enable stack logging:
set env MallocStackLoggingNoCompact=1
Thus, when your zombie is messaged, you can 'info malloc
0xDEADBEEF' (replace the address, obviously) and see where the bugger
was allocated.
Or you can also do all of the above in Instruments, using the Zombies
template. Though, frankly, Instruments has improved so much since
the Leopard release, I'd highly recommend doing your dev work on Snow
Leopard, if you have access.
Actually, all of the tools have improved so much, I do all of my dev
work in Snow Leopard, booting back to Leopard for final testing / QA
prior to release (for the very tiny handful of things I still do on
Leopard, anyway :).
