Cyber-SiKu opened a new issue, #2590:
URL: https://github.com/apache/brpc/issues/2590


   **Describe the bug (描述bug)**
   
   当在 bthread 
中使用标准库的std::mutex和std::condition_variable时,会导致线程丢失。线程没有退出也没有coredump，导致资源没有回收，引发死锁。
   
   **To Reproduce (复现方法)**
   
   测试用例
   https://github.com/Cyber-SiKu/brpc/pull/1/files
   
   **Expected behavior (期望行为)**
   
   
   **Versions (各种版本)**
   OS: centos7
   Compiler: gcc-11
   brpc:
   protobuf:
   
   **Additional context/screenshots (更多上下文/截图)**
   在日志中加了一些输出：

   运行程序可以看到程序死锁，启动了9个线程，并且输出的1.1和1.2并不能成对：

   gdb 中有8个线程，这与start启动的线程数量不一致。
