私はモノタッチにかなり慣れていないので、困惑するエラーが発生します。スライディング スタイル ビュー ( https://github.com/edgecase/ECSlidingViewController ) 用の Objective-C ライブラリへのバインディングを作成し、そのライブラリの使用中にネイティブ コードを実行している間に SIGSEV を取得しています (具体的には、発生します)。スライドコントローラーから下のビューを表示しようとすると)。

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

これに関する奇妙な部分は、iOS シミュレーターでアプリを実行したときにのみ発生することです。デバイスでは、すべて正常に動作しているように見えます。
誰が何が起こっているのか手がかりを持っていますか?
