firebase-ios-sdk: iOS 10 : Crashes in RCNConfigDBManager and FIRIAMActionURLFollower
[REQUIRED] Step 1: Describe your environment
- Xcode version: 11.4
- Firebase SDK version: 6.21.0
- Firebase Component: FirebaseRemoteConfig
- Component version: 4.4.7
- Installation method: CocoaPods
[REQUIRED] Step 2: Describe the problem
Steps to reproduce:
We’ve recently updated from version 6.17.0 to 6.21.0 and now we are getting crashes on iOS 10 (only). It seems to be related to RemoteConfig. We didn’t change anything in the code that uses remote config between these two releases.
The crashes are :
Plantage : com.apple.main-thread
EXC_BAD_ACCESS KERN_PROTECTION_FAILURE 0x00000000382f4000
Here are some stack traces :

Relevant Code:
Basically, from func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool
We call :
- FirebaseApp.configure()
- Performance.sharedInstance().isInstrumentationEnabled = false
- RemoteConfig.remoteConfig().setDefaults(fromPlist: “xxx”)
- (void)fetchWithExpirationDuration:(NSTimeInterval)expirationDuration completionHandler:(nullable FIRRemoteConfigFetchCompletion) completionHandler;
The crashes occur at launch.
Thanks for your help !

There might be an Apple bug building applications with Xcode 11.4 for 32 bit devices. See the discussion at #5233.
Can you confirm that all crashes come from 32bit devices? Is building with Xcode 11.3.1 a workaround?
@dmandar For me too. I used 6.19.0 too and we had a regression (this crash) in this current version.
@dmandar Our last sdk version was 6.19.0, and it worked well.
@Cafielo what last previous version worked for you?
