C valgrind错误：条件跳转或移动取决于未初始化的值

我有一个计划：

#包括
int调用（）{
int x=25；
++x；
返回x；
} 
int main（）{
INTP；
p=调用（）；
printf（“%d”，p）；
返回0；
} 

当我用

-g

选项编译程序并用valgrind运行它时，它显示：

我不知道为什么会出现这个错误

这是什么意思

他们怎么能破坏我的程序

如何删除它们？

这些不是来自您的代码，而是来自

/lib/ld-*。因此
是动态库加载器

这是一段被广泛使用的代码，我很难想象它有如此明显的bug，所以我认为valgrind给了你误报。您可能可以安全地忽略它们。
尽管这是来自系统库，与您的代码无关（看起来无害），但请确保您在
/usr/lib/valgrind
目录中有正确的.supp文件。与您的glibc版本相对应，将有一个部分用于抑制此类错误消息：

#-------- glibc 2.3.4/ Fedora Core 3
{
   dl_relocate_object
   Memcheck:Cond
   fun:_dl_relocate_object
}

也许你想检查一下valgrind的安装
 如果它是从自己的代码中犯下的，那么这个错误意味着什么？那么它会损害我的代码吗？是的，那么它可能是一个bug的迹象。例如，这将触发它：
inti；如果（i）printf（“Hello world\n”）。这是未定义的行为，因为
i
尚未初始化。
