I receive SIGABRT when working with NSUserDefaults

Question

The following line sometimes throws SIGABRT:

[[NSUserDefaults standardUserDefaults] synchronize];

I have not idea why it happens. By the way, the app is multithreaded.

In which thread do you send that message? – Jul 19 '11 at 12:05 — , Jul 19 '11 at 12:05

NSUserDefaults is thread safe, that's not the problem. You are over releasing some object in your defaults and synchronize is crashing when it finds it.

No, this is probably not the reason. – Erik Sapir Jul 19 '11 at 12:09
Can you enable NSZombieEnabled and see what happens? Is there any particular reason why you are running synchronize manually? – Jano Jul 19 '11 at 12:16

This can also happen if you added a Key Value Observer on a preference and did not implement

-(void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context
