我正在尝试调试一些应用程序，并且我想使用以下命令传递一些数据，但出现错误。

    ....
    ....
    (gdb) x/20x $esp
    Value can't be converted to integer.
    (gdb)

我的 GDB 版本如下：

您从 64 位系统运行它，因此您应该使用寄存器名称作为 rip 而不是 eip 等所有寄存器。

例如：

(gdb) x/x $rip
0x4004c8 : 0x4005d8b8

获取信息寄存器以查看所有（gdb）信息寄存器

(gdb) x/20x $esp
Value can't be converted to integer.

尝试x/20x $rsp或x/20x $sp
