Greetings all,
I recently discovered the command line tool 'leaks' and I've been
using it to try and identify and remove memory leaks from my Cocoa
app. Thing is I'm getting an awful lot of really strange leaks all of
objects whose names are prefixed by NSZombie_
Here is a short example:
Process 5552: 32569 nodes malloced for 4175 KB
Process 5552: 1980 leaks for 87344 total leaked bytes.
Leak: 0x02879600 size=1536 instance of 'NSZombie_NSConcreteData'
Leak: 0x0287da00 size=1536 instance of 'NSZombie_NSConcreteData'
Leak: 0x011cd680 size=240 instance of 'NSZombie_NSWindowAuxiliary'
Leak: 0x04a74510 size=240 instance of 'NSZombie_NSWindowAuxiliary'
Leak: 0x04a27770 size=240 instance of 'NSZombie_NSWindowAuxiliary'
Leak: 0x04a71640 size=240 instance of 'NSZombie_NSWindowAuxiliary'
Leak: 0x04a92990 size=240 instance of 'NSZombie_NSWindowAuxiliary'
Leak: 0x04a934b0 size=240 instance of 'NSZombie_NSWindowAuxiliary'
Leak: 0x04a98a50 size=240 instance of 'NSZombie_NSWindowAuxiliary'
...
Nearly all the leaked objects sound like they are private and part of
AppKit.
I've checked my project several times over to see if I've got
NSZombieEnabled enabled and I haven't, I've even specified it as
turned off but it seems to have no effect. So my question is whether
this is normal behaviour for the leaks tool or is something really
screwy going on? Are all my autoreleased objects getting leaked for
some reason?
Just as an FYI I've got the latest dev tools and I'm running on
10.4.3 incase that makes a difference.
Cheers,
Rory
