vinllen opened a new issue, #1997:
URL: https://github.com/apache/incubator-brpc/issues/1997
**Is your feature request related to a problem? (你需要的功能是否与某个问题有关?)**
目前程序core掉（非brpc问题，是我们程序内部bug），core栈只到brpc，我们用的是brpc+tcmalloc，是否有额外的参数能够看到完整的core栈：
```

**Describe the solution you'd like (描述你期望的解决方法)**
同一块代码导致的coredump，有的时候coredump能够打到程序中，有的时候打不出来（只能到brpc层），是否有配置上的建议，使得我们能够打印完整的core栈，已经开启了no-omit-frame-pointer，tcmalloc是链接的gperftools源码。
**Describe alternatives you've considered (描述你想到的折衷方案)**
**Additional context/screenshots (更多上下文/截图)**
