c – 二进制树堆栈溢出

我根据Alex Allain的 example found here创建了一个二叉树.它在向它添加大约5000-6000个元素后抛出了一个堆栈溢出异常.知道如何防止堆栈溢出？原因是insert()以递归方式调用自身.

这是我如何重构代码以避免堆栈溢出：

void Insert(Key_T key,Value_T val,QuickMapNode<Key_T,Value_T> *leaf)
{
    while (true)
        if(key < leaf->key)
        {
            if(leaf->left) leaf = leaf->left;
            else
            {
                leaf->left = new QuickMapNode<Key_T,Value_T>;
                leaf->left->key = key;
                leaf->left->val = val;
                leaf->left->parent = leaf;
                leaf->left->left = NULL;    // Sets the left child of the child node to null
                leaf->left->right = NULL;   // Sets the right child of the child node to null
                break;
            }  
        }
        else if (key >= leaf->key)
        {
            if(leaf->right) leaf = leaf->right;
            else
            {
                leaf->right = new QuickMapNode<Key_T,Value_T>;
                leaf->right->key = key;
                leaf->right->val = val;
                leaf->right->parent = leaf;
                leaf->right->left = NULL;  // Sets the left child of the child node to null
                leaf->right->right = NULL; // Sets the right child of the child node to null
                break;
            }
        }
}
