问题描述

gdp调试的时候查看寄存器信息提示 The program has no registers now.怎么解决？

源代码是这样的
#include ""stdio.h""
#include ""string.h""

char code[]=
x41x41x41x41x41""
x41x41x41x41x41""
x41x41x41x41x41""
x41x41x41""
x41x41x41x41""
x82x84x04x08""
x00"";

void copy(const char *input)
{
char buf[10];
strcpy(buf input);
printf(""%s n"" buf);
}

void bug(void)
{
printf(""I shouldn't have appearedn"");
}

int main(int argc char *argv[])
{
copy(code);
return 0;
}
使用gdb调试进行溢出攻击的时候，
(gdb) disasse main
Dump of assembler code for function main:

End of assembler dump.
(gdb) info all-registers
The program has no registers now.

求教～THX

解决方案

试试使用 r 命令后再使用 info all-registers

解决方案二：
应该是没有设置断点，break一下试试
