AngularJS Safari crash EXC_BAD_ACCESS (SIGSEGV)

Question

Речь идет об отключении приложения AngularJS Safari. Приложение случайно отключает Safari на настольном компьютере и iPad. Я понимаю, что что-то вызывает несуществующую запись в памяти. Как я могу отслеживать этот журнал для действий JavaScript/HTML/CSS?

Ниже приведен вывод отчета об ошибке Safari. Я обнаружил, что вызовы 22 и 44 в нитке, которая разбилась, выглядят несколько иначе, чем другие. Я удалил отчеты для потоков, которые не сбой. Я также удалил состояние потока (он превысил лимит символов).

Answer 1

В какой версии Safari вы видите это? И происходит ли с открытыми или закрытыми инструментами Dev?

Safari 7.0.1 глючит, я уверен, что обновление до более поздней версии исправит его.
