Description

We were running into strange crashes on a WIFI only iPad Mini running iOS v9.3.5 when WIFI was disabled, the error was:

libc++abi.dylib: terminating with uncaught exception of type std::logic_error: basic_string::_S_construct NULL not valid

We eventually traced it back to the following code, that only crashed when the error message returned from the OS contained a special character. See the comments where we force the error message to the one returned by the OS with a special character vs. a test message without that one character.

• (void)locationManager:(CLLocationManager*)manager didFailWithError:(NSError*)error
  {
  NSLog(@"locationManager::didFailWithError %@", [error localizedFailureReason]);

CDVLocationData* lData = self.locationData;
if (lData && __locationStarted) {
// TODO: probably have to once over the various error codes and return one of:
// PositionError.PERMISSION_DENIED = 1;
// PositionError.POSITION_UNAVAILABLE = 2;
// PositionError.TIMEOUT = 3;
NSUInteger positionError = POSITIONUNAVAILABLE;
if (error.code == kCLErrorDenied)

{ positionError = PERMISSIONDENIED; }

// Issue #1279 - seems cordova framework does not support characer ’ (Alt + 0180)
NSString *errorMessage = @"The operation couldn’t be completed. (kCLErrorDomain error 0.)"; //App crashes
//NSString *errorMessage = @"The operation couldn't be completed. (kCLErrorDomain error 0.)"; //App does not crash
//[self returnLocationError:positionError withMessage:[error localizedDescription]];
[self returnLocationError:positionError withMessage:errorMessage];
}

if (error.code != kCLErrorLocationUnknown)

{ [self.locationManager stopUpdatingLocation]; __locationStarted = NO; }

}

We were not able to replicate this issue on iOS v10+ though, however it did seem to be somewhat timing related as to when that specific error message was returned and therefore causes the crash.
