我很确定这是堆栈溢出。我是否正确，它是一个递归循环吗？如果不是发生了什么!

Answer 1

不，这不是堆栈溢出。非法访问位于 0x00007fd37a589ae0。 [NSView _recursiveDisplayAllDirtyWithLockFocus:visRect:] , 其代码中有 1875 个字节，试图跳转到那里，而这个内存区域是为数据保留的，而不是代码。特定的代码 [NSView _recursiveDisplayAllDirtyWithLockFocus:visRect:]不一定有错，也不一定是调用堆栈中出现的任何代码。崩溃可能是由调用堆栈中出现的函数(直接或间接)调用的任何函数中的错误的结果，并且该函数可能不再出现在调用堆栈中，因为它已完成执行并离开内存中的定时炸弹。

堆栈指针寄存器包含值 0x00007fff55df91d0，确认 0x00007fd37a589ae0 处的非法访问不太可能是堆栈溢出。

此外，如果您不是 Farm Hand 的作者，那么您对这份报告没有任何用处，只能将其发送给 Farm Hand 的作者(并希望此人是能够理解它的程序员)或启动用于长时间乏味的 session 的调试器。您在问题中建议的所有解释(递归、堆栈溢出)似乎都是错误的。
