在MAC上使用FLTK的C++中的gdb错误
问题描述：
我在C++中使用FLTK，当我改变了一个窗口小部件的值时，我的程序经常崩溃。我用gdb运行我的程序来复制错误，并在执行回溯时得到两个相似但不完全相同的错误。奇怪的是，回溯并没有在我的代码中列出任何函数，但它在代码中我不会指望出现错误，所以在我的代码中可能会出现错误来给出这些结果？在MAC上使用FLTK的C++中的gdb错误

任何想法？提前致谢。

free实现（您的第一个堆栈跟踪）内的任何崩溃通常是双免费或另一种堆损坏的迹象。
MacOS上的系统malloc有debugging features，您可以打开它，并且应该允许您将它靠近它发生的位置。
