AngularJS Safari崩潰EXC_BAD_ACCESS（SIGSEGV）

Question

這是關於一個AngularJS應用程序崩潰Safari.The應用程序在桌面和iPad上隨機崩潰的Safari。我知道有些東西正在調用內存中不存在的記錄。如何將該日誌追蹤到JavaScript/HTML/CSS操作？

以下是Safari錯誤報告的輸出。我發現在崩潰的線程中調用22和44看起來有些不同於其他線程。我刪除了沒有崩潰的線程的報告。我也刪除了線程狀態（它超出了字符限制）。

什麼版本的Safari你看到這個？開發工具打開還是關閉會發生嗎？

Safari 7.0.1是越野車，我打賭升級到更高版本將修復它。
