在自定义类型的向量(基本上是图形节点)上调用insert函数时,我遇到了一个奇怪的错误.以下是生成seg错误的代码:
69 for (int i = 0; i < size; i++) {
70 PDTNode * node = arguments[i]->getNode();
71 //addChild(node);
72 children.insert(it, node); // children is vector <PDTNode*>
73 it++;
74 node->addParent(this);
75 }
我仔细检查所有输入,一切正常,不是NULL.下面是我为seg错误获得的gdb堆栈跟踪:
