Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runt
有什么帮助可以防止这个错误被抛出？我已经尝试将停止音频的代码放入try-catch中，但它仍然会使应用程序崩溃。
我有一个SystemSounds数组，当我退出ViewController时，我想停止播放所有声音。如果当前正在播放声音，则代码执行正常。当一个声音完成并且下一个声音没有开始时，它似乎抛出上述错误。我停止音频的代码是：
try
{
if (_tracks != null) // an array of tracks that have to be played
{
for (int i = _soundQueue - 1; i >= 0; i--) // _soundQueue is the num of tra
{
_tracks[i].Item1.RemoveSystemSoundCompletion();
_tracks[i].Item1.Close();
}
}
_soundQueue = 0;
_tracks = null;
_playingAudio = false;
}
catch (Exception ex)
{
}
