C++ Eclipse:二叉搜索树节点>数据=变量似乎不起作用

构建成功，但运行时停止在

节点>数据 = 出价;

在以下函数中。因此，输出成功打印到"加载CSV文件888"cout语句。我不确定是什么阻止它运行该代码。

void BinarySearchTree::Insert(Bid bid) {
// FIXME (2a) Implement inserting a bid into the tree
cout << "Loading CSV file 333" << endl;
Node* node = root;
cout << "Loading CSV file 888" << endl;
node->data = bid;
cout << "Loading CSV file 777" << endl;
if (root == NULL){
//root->data = bid;
//root->left = 0;
//root->right = 0;
root = node;
node->left = NULL;
node->right = NULL;
cout << "Loading CSV file 444" << endl;
}
else
{
cout << "Loading CSV file 666" << endl;
Node* cur;
cur = root;
while (cur != NULL){
if (strToDouble2(node->data.bidId) < strToDouble2(cur->data.bidId)){
if (cur->left == NULL){
cur->left = node;
cur = NULL;
}
else{
cur = cur->left;
}
}
else
if (cur->right == 0){
cur->right = node;
cur = NULL;
}
else{
cur = cur->right;
}
node->left = NULL;
node->right = NULL;
cout << "Loading CSV file 5555" << endl;
}
}
}
