I am not sure why GDB doesn't work as desired after setting a breakpoint:
我不确定为什么在设置断点后GDB无法正常工作：
[jalal@mumble-36] (2)$ gdb --args ./server 200000 img

Reading symbols from /afs/cs.wisc.edu/u/j/a/jalal/fall2013/p5-linux/server...(no debugging symbols found)...done.
(gdb) b server.c:256
No symbol table is loaded. Use the "file" command.
Make breakpoint pending on future shared library load? (y or [n]) y
Breakpoint 1 (server.c:256) pending.
(gdb) c
The program is not being run.
Here's what in .gdbinit
这是.gdbinit中的内容
set auto-load safe-path /
Any idea what I am not doing or what am I doing wrong? I used to do the same steps previously!
知道我不做什么或我做错了什么？我以前做过同样的步骤！

根据消息：

No symbol table is loaded. Use the "file" command.
Make breakpoint pending on future shared library load? (y or [n])
it looks as though your binary has been compiled without debugging symbols, so breaking at server.c:256 isn't going to work (since there's nothing to indicate to gdb where line 256 is!). Recompile with -ggdb and try again with run.
它看起来好像你的二进制文件已经编译而没有调试符号，所以打破server.c：256是行不通的（因为没有什么可以向gdb指示第256行的位置！）。使用-ggdb重新编译，然后使用run重试。

@duskwuuf answer is right, however it is not the only reason of the error The program is not being run. I had the same problem, but because of bad gdb running.
@duskwuuf回答是对的，但这不是错误的唯一原因程序没有运行。我有同样的问题，但由于糟糕的gdb运行。
The program with commandline arguments must be run with --args option, like as @Mona_Jalal does: gdb --args ./server 200000 img
带有命令行参数的程序必须使用--args选项运行，就像@Mona_Jalal一样：gdb --args ./server 200000 img
