我要用有序的插入函数在 C 中创建一个链表。数组列表是单个链表的数组，我必须生成 10000 个随机数，有时我可以生成 300 或 400 个数字，有时它会失败并给我一个缓冲区溢出异常。我得到这个的原因是什么？
我认为这可能是因为我需要释放一些内存，但在我看来，我需要分配的所有内存，什么都没有。
当错误发生时，调用堆栈显示这一行：
struct Node *newNode = (struct Node *)malloc(sizeof(*newNode));
是导致异常的原因。
它可以在生成的数字较少的情况下正常工作，例如如果我做 100 个数字，输出看起来像这样： http ://gyazo.com/18a9ba87611f5676d6fa7b6229fc41e0 当然这不是完整的输出，但这就是想法。

如果需要，这是完整的调用堆栈-

这不是完整的调用堆栈。完整的调用堆栈长达数英里。
