У меня есть приложение quickfix .net. Я использую .net/c++ version of quickfixОшибка Quickfix: System.AccessViolationException
Иногда мое приложение вызывает эту ошибку, и я не могу ее поймать с помощью блока catch try. Длина сообщений об исправлении составляет около 3000. Я не получаю эту ошибку каждый раз. Это журнал событий:

Скорее всего, вы пытаетесь извлечь 'field', который не присутствует в исходном FIX сообщении. Можете ли вы вставить FIX messgae, который вы разбираете, когда происходит экспрессия. – DumbCoder
Я вставил исправление msg. –
Вы пытались отлаживать вообще? Никто не собирается тратить через это большое сообщение FIX, которое вы опубликовали. – DumbCoder
