[GitHub] [incubator-brpc] jiangdongzi commented on issue #2042: 普通线程中调用bthread_start_background100次，在函数中打印对应的stack 100次执行的都是一个值，对应的cur_tid都是0，我打印前是取出来对应的值赋值局部变量打印的

   这个简单的demo执行是正常的, 我们的服务器上打印不正常, 打印的所有cur_stack都是一个值, 所以的cur_tid都是0, 而, 这个demo不是 (基本完全一样的代码),  唯一的区别是, demo的 bthread_start_backgroud是在主线程执行, 而我们服务器上是在 pthread_create 出来的线程中执行的.  但是 bthread_start_backgroud 返回的tid是正确的值, 就是在真正的逻辑中打印的tid都是0, stack都是同一值, 但是看日志又是并发的, 不是串行的,  而打印的stack是一个值, 我理解应该是串行的, 这就矛盾了, 麻烦帮忙看看, 有什么可能导致了服务和demo的不同
