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.

Like WKSyntheticTapGesturestabilizer has been released and is still accessing its member variables
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 am trying to fix a bug that I am not able to recreate, it doesn't happen to my device (iPhone 5s) or in any iOS simulator but happened only once in an iPhone 7 of my client. When the client deleted and downloaded again the app, the bug disappeared, so I am searching for a ghost now.
I was able to get the crash log file from the clients phone and symbolicate it. Here are some useful informations I extracted:

So at the third line of the un-symbolicated crash report it says:
0x18d324df0 -[NSString stringByAppendingString:] + 112
and at the 4th line of the symbolicated crash report:
0x10469f928 -[AppDelegate initViewController] (AppDelegate.m:96)
In my AppDelegate at the 96 line I have this code:
NSString *backColorString = [#"#" stringByAppendingString:[myModel sharedInstance].theme.BackColor];
So the only thing that can be wrong with this, if the problem is indeed here(?) is that the
[HotelStay sharedInstance].theme.BackColor
must return nil or "".
The thing is that I tried both and I couldn't be able to recreate the problem. Is there something I am missing or doing wrong here?
if you use stringByAppendingString on an NSString than you end up with leaks because the pointer associated with the initial NSString moves around, pointing to the new string created by the append, whereas with NSMutableString, your pointer always points to that mutable string. I guess it should be the issue but what I am thinking is according to Apple Documentation The string to append to the receiver. This value must not be nil if its nil it will Raise a NSInvalidArgumentException.
The crash tools report a weird crash of my app.
It crashed at MDOSWebViewDelegate.
After listed all the symbols of binary with command nm -a myApp,
and still can't locate it from the crash stack.
I don't even know what features of these modules, it seems this module is from an System framework.

Any suggestion?
I am able to symbolicate my crash logs in xcode 4.5 EXCEPT for the last line. Specifically line 29 of the 'Last Exception Backtrace' and line 15 in the 'Thread 0' area in the crash log doesn't show the object or method call when all the other lines do. My code is CoachMe1.
Any ideas as to why this would be ?
