iphone – CoreFoundation中的CFStringGetLength中的iOS崩溃

我遇到了一个崩溃,对我来说,好像它是Apple处理MKMapView的goToDefaultLOCATIOn消息的方式中的一个错误.该消息依次调用[ALCitymanager localeWithCode：],该函数调用[NSLocale componentsFromLocalEIDentifier：],调用CFLocaleCreateComponentsFromLocalEIDentifier调用CFStringGetLength并发生崩溃.

有人可以帮我指出修复错误的方向,如果是我的代码导致这个,或者,帮助我找到一个解决方法,实际上,这是Apple的代码中的错误(不太可能？).

崩溃日志如下：
