应用程序在gpus_ReturnNotPermittedKillClient崩溃

我看到特定于在iOS 8上运行的应用程序的新崩溃。无法确定问题是什么，无法重现问题。 发生在App StartUp上，而App不直接调用OpenGL ES函数。

InitialViewController viewDidAppear方法第92行我从storyboard启动一个segue： [self performSegueWithIdentifier:segueIdentifier sender:self]; self是InitialViewController类。

有人可以帮我find这个问题的根源是什么。

如果它试图在后台执行OpenGL ES命令，应用程序将被终止。
