URL: https://github.com/apache/brpc/issues/3013
**Describe the bug**
关闭save_series,启动直接core dump
**To Reproduce**
**Expected behavior**
**Versions**
OS:
Compiler:
brpc:
protobuf:
**Additional context/screenshots**
在 LatencyRecorder::expose中有一个CHECK_EQ
```
CHECK_EQ(0, _latency_percentiles.set_vector_names(namebuf));
```
但在关闭save_series时，PassiveStatus::set_vector_names返回-1，导致core
```
int set_vector_names(const std::string& names) {
if (_series_sampler) {
_series_sampler->set_vector_names(names);
return 0;
}
return -1;
}
```
