我相當肯定這是一個堆棧溢出。我是否正確，它是一個遞歸循環嗎？如果沒有發生什麼事情！

Answer 1

不，它不是堆棧溢出。非法訪問在0x00007fd37a589ae0。 [NSView _recursiveDisplayAllDirtyWithLockFocus:visRect:]，其代碼中有1875個字節，試圖跳到那裏，並且這個存儲區域被保留用於數據而不是代碼。代碼[NSView _recursiveDisplayAllDirtyWithLockFocus:visRect:]的特定代碼不一定是錯誤的，或者確實出現在調用堆棧中的任何代碼段。這個崩潰可能是由於調用堆棧中出現的函數（直接或間接）調用的任何函數中的錯誤的結果，並且此函數可能不再在調用堆棧中顯示，因爲它已經完成執行並離開記憶中的定時炸彈。

堆棧指針寄存器包含值0x00007fff55df91d0，確認在0x00007fd37a589ae0非法訪問不可能是堆棧溢出。另外，如果你不是Farm Hand的作者，那麼除了將它發送給農場手的作者（並且希望這個人是那種能夠理解它）或啓動一個調試器進行漫長而乏味的會話。你在你的問題中提出的所有解釋（遞歸，堆棧溢出）似乎都是錯誤的。
