请提供详细的可复现的环境

@outer199 感谢反馈，目前我们暂时没有环境复现该问题。能否找到报错的commit 或者 提供一下报错时的输入命令和完整 log

Thanks, we do not need to open a new pr for this. We can use the previous pr such as #453 , and push all commits into the single branch~

We should follow https://github.com/bytedance/sonic/blob/main/CONTRIBUTING.md, pls rename the pr title and reedit the commit msg， such as `opt: the get&set way of hashmap using xxhash` Also, please add the xxhash license...

Thanks~

Thanks, and Sonic has updated a lot, we will close the PR
