I am running into a strange crash I'm having issues debugging. My scheme has both zombies and address sanatizer enabled.
I'm getting the error:
2015-09-05 06:56:16.240 asgaard[486:110984] *** -[CFString
boundingRectWithSize:options:attributes:context:]: message sent to

which is pretty unhelpful to me as its breaking on some assembly code.
I tried the memory history command which I'm not sure is what i need and got the following output:

Frame 8 is a function I wrote - and it is running in an async loop on the main thread - could that somehow be connected to this error?
The actual code line is:
578: [self coreGroundSpeed].text = [NSString stringWithFormat:#"%d Kts", coreSpd];
Any suggestions where/what to look at?

Can someone help please? Has anyone seen anything of this sort?
Sometime after writing code to my project, I noticed the debugger would pause my application and put lldb in the console and couldn't let me continue. I used NSZombies and I got this message : "-[NSThread threadDictionary]: message sent to deallocated instance". I have looked around but couldn't find any help what is causing this. When I print the backtrace I get:

Any help to find out whats going on will help tremendously!
Found out the problem was I had a label with a weak reference. I was hiding it for to long and it seems the garbage collection cleaned in up. So when I tried to send data to it, it was already dealloc.
Somewhere you are calling an instance method of any class and class object is nil.
I am new to Objective C, and cannot figure out the error I am facing right now. The app was developed by some other developer few years back, and I just have to change some images and upload back as new version (and underline API/webservice got updated). Everything was done fine, but one button in app is causing a crash.
We have two button in our main interface, one shows the listing near by user location, which works, and we have another to show all listing. The calling method for them is same, but when we use Show all listing interface in code it crash application with no error. in Debugger it shows (lldb) and generate SIGABRT in main appdelegate call.
Here is the button code
-(IBAction)btnAllResturantAction:(id)sender
{
[btnAllRestaruant setImage:[UIImage imageNamed:#"all_restaurants_tapped.png"] forState:UIControlStateNormal];
NSLog(#"SearchView : Button CLick for All Resturant");
#try {
HomeViewController *homeView1=[[HomeViewController alloc]initWithNibName:#"HomeViewController" bundle:nil];
[self.navigationController pushViewController:homeView1 animated:YES];
NSLog(#"SearchView: Button CLick complete");
} #catch (NSException *exception){
NSLog(#"Search View: Exception in All Resturant %#", exception.reason);
}
}
When in line by line debug, I can see Log message of "Button Click complete" visible in debugger window, but just after that it fail and crash application, I didn't see any other error message even after I try bt in Debugger window, it shows all framework code. Here is bt result anyways

Check if you have UIAlertView or animations in view before came back to your view. It seems you are initalize a view with it's local variable, wihout having express use self delegate, or you use removeFromSuperview for a view while actions still call it after remove.
I'm getting the following error randomly (and sometimes consistently on launch). It can happen when there are background threads and when there aren't and it seems to be a problem with the library so I'm having trouble tracking down the problem in my code. The breakpoint triggers on:
