c++ - 运行时检查失败 #2 - 变量“b1”周围的堆栈已损坏

Question

我的问题是，当我运行我的程序时，它告诉我“运行时检查失败 #2 - 变量 'b1' 周围的堆栈已损坏。如果有此异常的处理程序，则程序可以安全地继续。”

while (!feof(fp))
		{
			fscanf(fp, "%2X", &a1[0]);
			fscanf(fp, "%2X", &a1[1]);
			fscanf(fp, "%2X", &a1[2]);
			fscanf(fp, "%2X", &a1[3]);
			fscanf(fp, "%2X", &a1[4]);

			fscanf(fp, "%2X", &b1[0]);
			fscanf(fp, "%2X", &b1[1]);
			fscanf(fp, "%2X", &b1[2]);
			fscanf(fp, "%2X", &b1[3]);
			fscanf(fp, "%2X", &b1[4]);

			if (foo==foo)
			{
				foo....
			}
		}
