+[NSObject(Property) mj_enumerateProperties:] 崩溃
为了排除你自己的问题, 请写一个 Demo
线上日志收集到的崩溃，不是必现
描述bug json转model崩溃，最近收集到不少类似的崩溃，堆栈的末尾基本上都是这种：

8 MJExtension 0x000000010afffb1e +[NSObject(MJKeyValue) mj_objectWithKeyValues:context:] + 448
都是不同的类调用 mj_objectWithKeyValues 后崩溃，不是某个单独的类。
运行环境
- macOS
- 涉及到从 10.15 ～ 12.3多个系统版本。
- Xcode 11
下面是一个崩溃的例子。
