I am testing my app out, pushing it pretty hard, and I'm getting it to crash (black screen, image doesn't save, drops back to springboard). However, I get no crash reports logged in the console. When I test using profiler all I get is a message saying the target died, but it gives no clues.
In the organiser I got the device crash logs which gives me this which I believe is telling me I'm sending a message to something I've released (objc-msgSend + 22)? Am I on the right track here?

If you suspect that you are overreleasing something, try running your app with NSZombie enabled. (how to enable NSZombie)
You can set exception breakpoint to print backtrace in console.
sometimes that happens when you set an object as an observer for notifications, like
[[NSNotificationCenter defaultCenter] addObserver //details
and don't remove it from the observers list when it's released.
the system tries to send a message to it, and the app crashes because it's not there.
try adding
[[NSNotificationCenter defaultCenter] removeObserver:self];
in the dealloc function. (even if you're working with arc, create a dealloc function, and write that in it).
good luck

My app relatively often crashes with SIGSEGV. Unfortunately, I can not reproduce the crash and only see crash reports in Hockeyapp. I tried turning zombies on, too.
Looking at the crash report it seems that app crashes when processing touches (when user scrolling or something like this). No my app code mentioned in the stack trace.
The question is: how is it possible to have memory issue in this scenario? What would you recommend to reproduce and fix the issue?

I get the following crash log from Crashlytics for my app. My code do not call msgpack_zone_free or msgpack parse method at all and so I'm confused how that happened. I'm unable to reproduce this crash myself so I'm left to analyze the issue from the crash report itself. Any pointers to what I need to check will be very helpful.
This is not a case of low memory as I see free memory from Crashlytics.

Thanks.
I am not able to reproduce this crash but received this kind of crashes multiple times from production build. In my app tab bar is loaded from storyboard only and tab bar is always hidden all the time.
Does it's main cause is low memory? Any guess, how to solve or reproduce this kind of problems

From you crash log, line 5

seems like you generate your attribute string based on
- (NSAttributedString *)attributedSubstringFromRange:(NSRange)aRange
Maybe set a break point at that code, and check if your string length is larger than or equal to the range.

Not sure if this is the case for you, but I've had a similar crash caused by a button in an UIView trying to invoke a callback method on a already released object. The UI was displayed, and then the object was released.
I'm calling methods dynamically by name. this is the code I'm using:
NSString *methodName=[NSString stringWithFormat:#"%#HintButton",stringForPredicate];
SEL s = NSSelectorFromString(methodName);
[self performSelector:s withObject:hItem];
I Checked and s value is
AnotherSoundHintButton
I have the following method in my code:
- (void )AnotherSoundHintButton:(HintItem*) hItem {
[self PlaySound:hItem.hint];
}
but when I run my app I'm getting the following error:
