Crash report

["mike1" <nginx-forum@xxxxxxxx>]

Здравствуйте!
У меня Gentoo 64 bit. После установки push module
nginx начал трапаться примерно раз в 2
часа (нагрузка совсем не большая. При
более интенсивной нагрузке раз в 15
минут). Понимаю, что не совсем по адресу,
но на местном github-е никакой реакции не
последовало. Также не воспоследовало
реакции на мое письмо разработчику push
module.
Как я понимаю, причина падения в том,
что не проходит какая-то проверка в nginx
(range in overlapped buffers), может быть, уважаемые
разработчики nginx посоветуют, что можно
сделать (например, пересобрать nginx в 32
bit).
Я собрал debug-версию и получил backtrace.
