You enabled the datachannel function which caused a crash, however I can't see which line caused the crash.

Could you try debugging with gdb and give me the backtrace stack?

Datachannel should be stable, I think there might be other reasons for the crash.

你这个开启了datachannel功能这个导致崩溃的但是看不到具体崩溃在哪一行可以gdb调休下然后给下bt栈不？

datachannel应该是稳定的我觉得可能是其他原因导致崩溃

Here is the translation:

I do not have a datachannel option on the website, as shown in the above figure, gdb bt information.

网页上我没有选datachannel选项，上图是gdb bt信息

It seems I know the cause now, possibly it's due to the problems with the usrsctp library I used, which I obtained from an unofficial code library. I've already replaced it with the official library, and currently the testing is normal, I'll run it for a while to see if there are any issues, and if everything goes smoothly by tomorrow, I'll come back and close this issue.

大概知道原因了，可能是我用的usrsctp库的问题，下了个非官方的代码库。已经更换了官方的库，目前测试正常，我这边跑一段时间老化看看，跑到明天没问题的话，我过来把这个issue close掉。

Results are normal, close this issue.

测试正常，关闭该issue
