gflags静态库和共享库同时存在导致。我是选择手动编译gflags，在编译时为cmake指定选项`-DBUILD_SHARED_LIBS=1`，只编译共享库，可解决问题，具体参考[这里](https://github.com/sunzhenkai/cooking/blob/5022774c0185cf140c90553d837fc247f9586d67/c%2B%2B/universal/third/install.sh#L73)。如果是使用命令安装，可以尝试先移除`/usr/local/lib/libgflags.a` 和 `/usr/local/lib/libgflags_nothread.a`，然后重新编译brpc。
如果遇到下面这个异常，类似的原因，移除静态库。
```
ERROR: something wrong with flag 'help' in file '/Users/wii/Git/cooking/c++/universal/third/build/gflags-2.2.2/src/gflags_reporting.cc'. One possibility: file '/Users/wii/Git/cooking/c++/universal/third/build/gflags-2.2.2/src/gflags_reporting.cc' is being linked both statically and dynamically into this executable.
```

不能，升级了pb2.5，gflags2.2.1, 通过preload加载，能避免flags重新reload注册问题

BRPC_VALIDATE_GFLAG这个地方会引用不可预知的引起动态库加载的退出，有啥办法给解决一下么？
