Thanks for your reply.
You can't set NSZombieEnabled after a program has started running.
You need to set it as an environment variable and restart your app.
Actually you can, or at least I have, in many other projects to good
effect. I always figured as long as the deallocated object was
created after I set the runtime variable, a zombie would be swapped
in as needed. Was it just luck?
Well, waddya know! You can. Thanks for the correction.
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 :).
No doubt! I still regularly work on and target Tiger, so I realize
my workflow is archaic :P
In any case, it seems like there's something really weird going on
with this one project. I can't seem to touch any Cocoa from gdb,
though other calls are fine:
(gdb) po [NSArray array]
Could not find OSO file: ""
(gdb) p/x (void*)CFDictionaryCreateMutable(0, 99, 0, 0)
$1 = 0x185ea00
(gdb) p/x (void*)malloc(99)
$1 = 0x323bb0
My target is configured to link with the Cocoa framework. Perhaps I
should take this to the XCode list, though if anyone has any
suggestions I'd be happy to hear them :)
Are you trying to do remote debugging?
