我正在尝试破解破解版。我已经抓住了标志，因为我看到了代表标志的字符串变量。我想以另一种方式捕获标志，我想在比较字符串时设置断点。我想使用radare2。
当我使用dc命令运行应该停止到我设置的断点的程序时，我收到消息TO DO continue。我不知道为什么。我希望收到以下形式的消息：
string 1 : TheStringIEnter string 2 : TheFlagOfTheChallenge
这是我执行的命令：
radare 2 -d ch1.bin
s sym.main
aaa
pdf
VV
:
:> db 0x08048705
:> dc
TODO continue
:>
这是 pdf 命令的输出：
