C++ 我能'；无法找到此分段错误的来源：11错误

我确实意识到有很多关于这个错误的帖子，但是我已经浏览了其中的一些，似乎仍然无法将它们应用到我自己的代码中。我想我有某种内存错误，但我不知道是什么原因造成的，也不知道如何解决。我已经包含了我认为导致问题的代码段。下面是代码应该做的：我已经将图像分割成不同的彩色补丁（这很成功）。现在，我希望用户能够点击一个补丁，并有整个补丁颜色浅紫色。重新着色应延伸到选定面片的边界或图像的边缘，以先到者为准。下面包含的函数获取鼠标单击的x、y坐标，以及用户单击的补丁的id（由颜色确定）。它将对应于该x，y坐标的像素添加到堆栈中，然后查看是否有任何与我们的像素直接相邻的具有相同id的像素尚未重新着色。如果有，我们再次调用该像素上的函数。当我们发现自己没有新的像素可移动时，我们会从堆栈中弹出该像素，然后返回到尚未耗尽的最后一个像素。我认为这是一个内存错误的原因是，我的函数实际上在小的彩色补丁上工作，但是当它必须重新调用大的补丁时，它会崩溃。提前感谢您的帮助

cout note：“修补过的”函数检查像素是否已重新着色。非常确定此部分工作正常。您的操作系统是否应用了所有当前修补程序？抱歉，我不确定您的意思。我使用的是mac，如果有帮助的话。我已通过安装当前Solaris修补程序解决了类似问题。我不知道mac。我们无法运行您的示例（这不是一个最小、完整且可验证的示例，请参阅），因此很难真正提供帮助。我的建议是学习使用调试器（可能是MacOS上的LLDB）。使用此工具，您将很容易找到99%的seg故障。
