geblue opened a new issue #1369:
URL: https://github.com/apache/incubator-brpc/issues/1369
coredump的具体位置在 `error_code
==0`的分支里`static_cast<google::protobuf::Closure*>(data)->Run();` 这句。有个疑问是
`ResetNonPods`里为什么一定要调用 `RunOnCancel`呢？如果之前已经满足了cancel的条件，`RunOnCancel`
以及`data` 代表的回调函数已经被调用过了，这时候`data` 对应的closure已经被删除了吧, 这时候`ResetNonPods`再调用
`RunOnCancel`,是不是有问题？
