I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Thanks for reporting, @FenWangSiCheng. Based on this related issue, it seems like the _Block_copy crash is caused by memory corruption. As mentioned there, could you try reproducing the issue locally with zombies or asan?

Hey @FenWangSiCheng. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!
