GDB重置配置

Question

编辑:我先尝试用sudo apt-get autoremove gdb重新安装gdb，然后再用sudo apt-get install gdb重新安装。仍然不能解决问题。

原始问题：

所以最近，也就是大约3个小时前，我安装了valgrind来检查内存泄漏，现在我尝试编译一些东西并运行GDB (终端或在Eclipse中)，所有的malloc/calloc命令也都在一步一步地进行调试。

测试文件：

#include<stdio.h>
#include<stdlib.h>

typedef struct tem{
    int i;
} name;

int main() {
    name *t;
    printf("EASD");
    t = malloc(sizeof(name));
    return 0;
}

Eclipse调试器错误(仍然显示malloc和etc函数中的变量)：

Can't find a source file at "malloc.c" 
Locate the file or edit the source lookup path to include its location.

使用:cc -g -o asd a.c编译

已使用:gdb asd进行调试

终端：

(gdb) run
Starting program: /home/userName/workspace/as/asd 

Breakpoint 2, main () at a.c:10
10      t = malloc(sizeof(name));
(gdb) step 18442
Single stepping until exit from function _fini,
which has no line number information.
Single stepping until exit from function __do_global_dtors_aux,
which has no line number information.
Single stepping until exit from function _fini,
which has no line number information.
EASD33  ../sysdeps/unix/sysv/linux/_exit.c: No such file or directory.
(gdb) step
[Inferior 1 (process 6621) exited normally]

无断点的GDB：

(gdb) run
Starting program: /home/userName/workspace/as/asd 
EASD[Inferior 1 (process 6631) exited normally]

我的问题是，如何重新配置/重置GDB，以便像以前那样跳过标准库函数？

从另一台计算机：

(gdb) run
The program being debugged has been started already.
Start it from the beginning? (y or n) y
Starting program: /home/userName/a.out a.out
warning: Could not load shared library symbols for linux-gate.so.1.
Do you need "set solib-search-path" or "set sysroot"?
Breakpoint 1, main () at a.c:10
10      printf("EASD");
(gdb) step
11      t = malloc(sizeof(name));
(gdb) step
12      return 0;
(gdb) step
13  }
(gdb) step
0xb7e067c3 in __libc_start_main () from /usr/lib/libc.so.6

现在，多亏了gdb7.4，我不得不使用(gdb) skip file malloc.c。

我希望能有其他方法来恢复GDB的功能，这样我就不必手动添加所有标准库的源文件(我尝试过(gdb) skip file stdlib.h只是为了让那些想知道的人知道)。
