我的GDB为什么会这样呢，以前还好的，不知什么时候就出了这种怪毛病

调试的时候出现这种情况

(gdb) break main

(gdb) run
Starting program: /home/yyy/mine/c/add
warning: Child process unexpectedly missing: 没有子进程//这一行比较郁闷，哪位知道怎么回事，谢谢了。

Program terminated with signal ?, Unknown signal.
The program no longer exists.
You can't do that without a process to debug.

Using host libthread_db library "/lib/tls/libthread_db.so.1".??
说明你的系统使用NPTL，NPTL需要TLS的支持，用ldd 就可以看到libpthread.so应该是位于/lib/tls目录下的。
