обработка nginx-ом stderr полученного от fastcgi сервера

[Alexandr Gevlichenko]

Работает связка nginx+php-fpm.(nginx 7.22, centos 5.2)
При получении от php-fpm сообщений в stderr(warnings&notice) nginx не верно обрабатывает их, поведение напоминает переполнение буфера для stderr.
Вот пример php скрипта который воспроизводит ошибку:
<?php
$array = array();

for ($i = 1; $i < 20; $i++)
{
        if ( $array[$i] == 1) {
                print "test\n";
        }
}
print "done\n";

?>

При $i<20 работает как положено, в лог ошибок пишется:

2008/11/27 18:40:19 [error] 5656#0: *4218 FastCGI sent in stderr: "PHP Notice:  Undefined offset:  1 in /home/www/host/nginx.php on line 6
