valgrind显示了这样的错误..

我的代码：请在启动后检查代码的所有初始化和变量的使用。在第一行。 83它说没有初始化......是吗？我不明白..请帮助。
/*Declaration*/
42 int i = 0;
43 int a[4]={0};
44 char cstr[80];
45 memset(cstr,0,80);
46 int largest = 0;
if(largest == 3)
82 {
83 strcpy(cstr,str_concat(v[1],v[2]));
84 printf("\t%s%s\n\n",cstr,v[3]);
85
86 }
虽然我已初始化每个变量仍显示valgrind错误该怎么办？
