使用cmake编译example里echo_c++进程启动即报Segmentation fault: 11

[SillyBoyenjoy]

Describe the bug (描述bug)
请问为什么我用cmake编译example里echo_c++里的echo_server进程启动即Segmentation fault: 11，但是直接用Makefile的make编译正常？

Versions (各种版本)
OS:macOS Monterey 12.2.1
Compiler:Clang
brpc:1.3.0
protobuf:3.17.3
cmake version 3.21.3

CMake Deprecation Warning at CMakeLists.txt:18 (cmake_minimum_required):
Compatibility with CMake < 2.8.12 will be removed from a future version of

Update the VERSION argument value or use a ... suffix to tell
CMake that the project does not need compatibility with older versions.

贴下core栈信息：

1. ulimit -c unlimited 开启coredump
2. gdb echo_server ${coredump} 查看core栈信息

是mac才会有的问题，以下是lldb的backtrace：

看着不太像，编译没开debug吧

[SillyBoyenjoy]

应该打开了，dyld是ios系统main执行前的动态链接器？我把LINK_SO打开后bt好像详细了点，问题似乎出在class_name.cpp里面？

@SillyBoyenjoy 可以试试PR #2037

[SillyBoyenjoy]

class_name.cpp的问题修复了，后面level db的动态库加载也出现了coredump，采用静态库编译解决了。

@SillyBoyenjoy 确定问题是修复了吗，今天新clone的代码，运行cmake生成文件，执行就报错
