错误消息glibc检测到Malloc(）:内存损坏(快速）

我最近收到了这个错误。奇怪的是，我并不总是收到这个错误消息。。。

以下是我正在做的。。。

我正在动态地创建一个类的n个对象，并将它们存储在向量（C++）中。然后使用迭代器访问每个对象，并尊重它访问对象的成员。我也在阅读一些文本文件，所以在运行时手动编辑它们。我不知道我应该把代码的哪一部分放在这里，但这正是它崩溃的地方：

if( last_op_number == 1 ){
    it = n_bots.end();// Grabs iterator and go to the end of the vector; This is where the last OP1 bot is located
    bot *botop1 = &(*it); // Dereference iterator to have a pointer to that specific bot
    /* 3) Set the real buy and sell prices */
    botop1->real_bpsp(price_ex1,price_ex2);
}
// Clear text files
OKC->clear_pos();
OKC2->clear_pos();
updates_balance(); // Updates balances
green_light = 1; // Tell bot manager that we are good to go!

你知道发生了什么事吗？

谢谢！
