【已解决】【TuyaOS SDK】tuya mqtt上线后，程序执行段错误的问题

[19926824531]

上面发错文件了，重新发一下

[19926824531]

主业务接入流程有啥问题吗

[pippin-bobo]

tuya_handle_dp_cmd_jsons
tuya_handle_dp_query_jsons
initTuyaMediaService
startTuyaService
这部分代码看不到，还有一点流媒体初始化最好是放在mqtt上线之后调用，但是这个和崩溃无关

[19926824531]

缺失的流程看下附件
另外TUYA_IPC_av_start是在mqtt上线之后才会执行操作的

[pippin-bobo]

流程没看出什么问题 ，可以尝试
1）tuya_handle_dp_cmd_jsons tuya_handle_dp_query_jsons 相关处理直接返回
2）mqtt上线后，直接sleep，不要做任何主动操作看看
3）捕捉一下SIGSEGV，直接退出程序，不要继续运行了
多复现几次提供下日志附件

[19926824531]

做了上面说的问题尝试，还是崩溃
附件是对应的问题log

[pippin-bobo]

有多次崩溃得日志？看上去涂鸦服务运行得没什么问题；有没有启动和涂鸦无关得任何业务，可以全部关闭掉（包括音视频数据采集部分）

[19926824531]

按照上面的要求，抓了3次

你好，我这边有试过用gdbserver来调试程序，但是libtuyaos.a去掉了符号表，看不到信息，链接时加-rdynamic参数也会编译不过。

和应用层status_changed_cb没啥关系，我初始化时把这个置为NULL，程序运行到下图这个地方还是照样崩溃
麻烦检查一下SDK这个操作附近的代码逻辑，看崩溃可能和哪个因素有关。
