waruto210 opened a new issue, #3239:
URL: https://github.com/apache/brpc/issues/3239
**Describe the bug**
brpc服务运行过程中coredump，查看corefile，发现是builtin_service导致的

应该是LOG(FATAL)主动进行的abort导致了coredump，但我疑惑的是，为什么会走到LOG(FATAL)这里

coredump在下面这一行，id是一个uint64_t类型的，很奇怪
```
LOG(FATAL) << "Invalid VRefId=" << id;
```
