看样子是你的 thread function 抛了一个异常，但是没有 catch。

 79     try
 80     {
 81       func_();
 82       muduo::CurrentThread::t_threadName = "finished";
 83     }
 84     catch (const Exception& ex)
 85     {
 86       muduo::CurrentThread::t_threadName = "crashed";
 87       fprintf(stderr, "exception caught in Thread %s\n", name_.c_str());
 88       fprintf(stderr, "reason: %s\n", ex.what());
 89       fprintf(stderr, "stack trace: %s\n", ex.stackTrace());
 90       abort();
 91     }
