While running my ios app a user has encountered the following error. It has only happened once and I cannot figure out how to repeat the error. Could someone please interpret the following stacktrace to help me find the cause of the error.

I have been trying to integrate a new SDK (from Layar) in my app that already contains the Realm SDK.
The app was working fine up until now (with Realm). As soon as I add the Layar SDK following the steps in the link above (I don't actually call any functionality, I just add the framework and dependencies), the app crashes on launch at the Realm config, with the trace below.
Any ideas as to what might be causing the behaviour?

I have the following crash report but I can't figure out the cause of this crash. This crash appears quite frequently but the pattern varies at each time. Many thanks!

I am assuming that you download some information from the web and are trying to create a string with some parts of that information:
6 CoreFoundation 0x00000001866bc2bc _CFStringCreateWithFormatAndArgumentsAux2 + 272
7 Foundation 0x0000000187502448 -[NSPlaceholderString initWithFormat:locale:arguments:] + 172
Where ever you are using information that you fetched from the Internet, you should first check if that information is valid and respects the right format you expect. Therefore, I recommend you to validate the information before using it.
this might help you:

I'm getting a bizarre crash in a UIWebView where, somehow, MPVolumeView is somehow being instantiated by the OS, and not in the main thread. As a result, the application crashes.
Nowhere in my code is MPVolumeView being used or called, so I'm not sure what I should be doing here. The crash was not present in iOS 7 and only started to present itself in iOS 8.
Here's the traceback immediately before the crash:

You have a framework that "ensures" no UIKit methods are called on a background thread. However, as you see, this kinds of frameworks are not recommended in a production environment, only in a debug environment.
This is an Apple framework bug. It has been reported, and you should create a bug report as well.
Make sure to update your helper framework to the latest version:
https://gist.github.com/steipete/5664345
My recommendation would be to surround this framework with #if DEBUG statements. This should not be running on production code. Even the author of the framework says so:
You should only use this in debug builds. It doesn't use private
API, but I wouldn't ship it.
This iPhone App will dial and hangup a call automatically. It works on jailbroken devices.
Sometimes it will crash when hanging up a phone call.
What is the problem and how do I fix it?

It looks like you have a bogus file descriptor that its trying to close. The address ends in "fade2dead", which is likely a special value to indicate freed memory. Since I don't see any of your code in the stack trace, it's likely that something is overwriting memory used by the FreeType library. I'd look for other memory stompers in your code using GuardMalloc or other similar memory tools to track down what it could be, as it's not obvious from the above stack trace.
