Valgrind为什么说条件跳转或移动取决于静态数组的未初始化值？

问题描述

我不明白为什么这个简单的程序可以正常工作，但是当我用Valgrind检查它时，给了我太多错误。

#include<stdio.h>

int main()
{
    char input[10]  = {'a','b','c','d','e','f','g','\0'};
    while (fgets(input,9,stdin))
    {
        printf("\nComplete line: %s\n",input);
    }
    return 0;
}

这是我从valgrind得到的

我使用程序

我正在使用Kubuntu并进行编译：

gcc -DEVAL -std=gnu11 -g -static -o program program.c

不幸的是，由于学校项目，我不能使用其他编译选项
