LIST_ENTRY已损坏（即双重删除）。不知道为什么

Question

我正在使用youtuber JavidX9的一些技巧在控制台中制作一个简单的游戏。当窗口和缓冲区大小正确时，所有内容都会正确显示，对于尝试运行它的任何人来说都是FYI。当我尝试在调试时关闭应用程序时，我的问题就出现了。有时如果我通过随机移动屏幕周围的字符来搞定它就会破坏它。我得到的错误是标题中列出的错误。但在那之后，我收到一个链接器错误，告诉我该进程仍在运行（我找不到）。因此调试是一场噩梦。我已经好几天都在寻找这个问题的答案，希望你们中的一个C ++神可以帮助我。代码很短。

编辑：刚刚发现了一些新信息。如果我启动该程序，并且什么都不做，它将在大约一分钟后崩溃。潜在的线程问题？

Answer 1

我解决了这个问题。我的地图数组大于我的屏幕数组导致了问题。我无法深入解释这是如何导致错误的，但确实如此。添加2d相机后，将其锁定到播放器坐标，并将其夹在地图阵列的边框，它现在工作正常。我现在有一整套其他问题要处理，但是这个问题可以标记为已解决。如果其他人可以深入解释为什么这个问题会令人惊讶。感谢。
