运行环境
EasyAR SDK Basic Version 2.2.0
Unity 5.6.1f1(64bit)
win10
问题：第一次出现崩溃是将ImageTraker.SimultaneousNum 设置为20, 前后进行多次 ImageTarget Bind后崩溃；
将ImageTraker.SimultaneousNum 设置为1后不再出现，第二次将CameraDevice Close() 再 OpenAndStart(),进行多次绑定后 又出现了崩溃的情况。崩溃不固定出现在某一次绑定，并且重新 OpenAndStart CameraDevice后 同一个ImageTarget对象的 OnTargetLoad 被调用两次，OpenAndStart多少次，OnTargetLoad就会被回调多少次。 以下是和debug日志
