我正在解决有关Leetcode的Defanging IP地址问题，当我在本地运行它时，它可以很好地工作：
char * defangIPaddr(char * address){
char *defangedAddress;
defangedAddress = malloc(sizeof(address) + 10);
int j = 0;
int length = strlen(address);
for (int i = 0; i < length; i++)
{
if(address[i] == '.')
{
defangedAddress[j] = '[';
defangedAddress[j+1] = '.';
defangedAddress[j+2] = ']';
j = j+3;
}
else
{
defangedAddress[j] = address[i];
j++;
}
}
return defangedAddress;
}
但是当我尝试在leetcode上运行时，出现此错误：

我尝试在本地安装GDB进行调试，但是，我收到GDB错误：
(No debugging symbols found in ./defanging-an-ip-address)
我看过Valgrind，但是没有很多经验，所以我完全不了解如何调试和弄清这一点。
我知道我可以用另一种语言来解决它（我在JS，PHP，Python上有一些经验），但是我想钉C，因此试图弄清楚我要去哪里哪里以及我需要做什么。修复它，而不会灰心和失去希望。
谢谢！
