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。
