🐛 [firebase_crashlytics] terminating with uncaught exception of type std::__1::system_error: mutex lock failed: Invalid argument

[Tom3652]

Bug report

Describe the bug

I am getting this crash on iOS from Crashlytics and it seems to be an actual crash of the firebase_crashlytics plugin.
Here is the trace :

It is marked by the fresh signal which really makes me think that this happened when crashlytics tried to send the report after another issue in a previous session.

Steps to reproduce

Unfortunately i have no idea how to reproduce this, it happened 4 times.
However, as i see an "Invalid Argument" exception, i can provide the way i am using firebase_crashlytics to catch various types of errors in my app :

void registerOutsiderErrors() {
  FlutterError.onError = (FlutterErrorDetails details) {
    FlutterError.presentError(details);
    FirebaseCrashlytics.instance.recordError(details.exception, details.stack);
  };
  Isolate.current.addErrorListener(RawReceivePort((pair) async {
    final List<dynamic> errorAndStacktrace = pair;
    await FirebaseCrashlytics.instance.recordError(
      errorAndStacktrace.first,
      errorAndStacktrace.last,
    );
  }).sendPort);
}

void main() async {
  runZonedGuarded(() async {
    WidgetsFlutterBinding.ensureInitialized();
    registerOutsiderErrors();
    await Firebase.initializeApp();
    runApp(const MyApp());
  }, (Object error, StackTrace stack) {
    FirebaseCrashlytics.instance.recordError(error, stack);
  });
}

And i am also using a custom method :

static void logError(dynamic error, {StackTrace? stackTrace, String? reason}) {
    FirebaseCrashlytics.instance.recordError(error, stackTrace ?? StackTrace.empty, reason: reason ?? "");
}

Maybe this is due to a null error as input ?

Expected behavior

The app should not crash.

@Tom3652
Thanks for the report. Is that the only crash log you get or there's more ? If so, please provide us the same.
Also, is there a way for you to symbolicate the crash, that'll help to analyze it better ?
There's almost similar stack trace filed which could be same / similar to yours.

Thanks @darshankawar, it seems that you are right and i have a very similar issue to the one you pointed out.
Here is the most detailed trace that i can find :

Yes, looks very similar to the one I linked, may not be exact or very close and another one resembling the same crash was fixed, flutter/flutter#90783, so may be you can try to switch to latest master and see if you still get such logs or not.

Alright thanks, i will update and see if this still happens.
