ExecutionEngineException -在iOS运行时错误与parse.com SDK

我们正在使用Unity3d(版本5.0.1p1)为iOS和android创造一款游戏，因为我们使用的是Parse.com数据服务，所以我们自然会使用它来执行远程推送通知。

问题在于，在构建游戏并在测试设备(iPhone 4s iOS8.1.2)上运行后，我们在游戏开始时会遇到一个我们无法解决的执行引擎异常。下面是例外:

这个问题刚刚出现在新的Unity Parse SDK 1.5中(包含PNS功能)。我们所知道的是，运行一个空的项目，只有解析sdk很好，通知工作很好，但在我们的实际项目中，由于异常，设备不注册的通知在解析，所以我们假设有一种冲突之间的解析和我们正在使用的其他工具之一。

仅供参考:我们正在使用IL2CPP构建通用架构(我们也在构建。net 2.0子集，但我不认为这与问题有关)。

感谢您的宝贵时间和回答。

我们试着用Mono(2.x)来构建，结果出现了几乎相同的异常:

希望它能带给你们更多关于这个问题的细节。

更新2::

我们确切地知道是什么导致异常发生，不幸的是我们无法控制它，当我们注册通知时，我们这样做:

using NotificationServices = UnityEngine.iOS.NotificationServices;
using NotificationType = UnityEngine.iOS.NotificationType;
        /*
         .
         .
         .
         */
        void ACalledFunction ()
        {
            // Ask for permission for push notifications (Can Receive deviceToken)
            #if UNITY_IPHONE
            NotificationServices.RegisterForNotifications(
                NotificationType.Alert | 
                NotificationType.Badge | 
                NotificationType.Sound);
            #endif
        }
    }

更新15/06/2015:解析Unity SDK 1.5.1 (il2cpp脚本后端)

当尝试注册解析PNs时，我们仍然有相同的错误:
