The implementation logic differs between the C++ and JS libraries.

How to reproduce the crash?

1. create a producer then close it.
2. create a producer again, the app crashed.

I'll take a look as soon as I can. Feel free to create a PR if you wish.

Could you please provide a core dump traces showing the problem?

I actually encountered this issue while testing on iOS. When the program crashed, I compared the implementation logic in both JS and C++ and noticed a discrepancy; simply modifying the C++ code to match the JS version resolved the problem.I also undertook a significant amount of other work to get libmediasoupclient running on iOS.

I've tested this and I see no crash. Please provide us with more details, or with the PR fixing this (which should be the corresponding sync with ortc.ts).
