Segfault nginx 1.1.19

April 23, 2012 12:16PM
Здравствуйте!

После обновления с 1.1.18 до 1.1.19 (с аналогичными параметрами сборки) воркеры начали падать с 11 сигналом на двух location. Добавил --with-debug при сборке, 'error_log error.log debug;' в конфиг, получил кору. Вот локейшены:

location ~ ^/m/(.*)/(.*)? {
set $username $1;
set $newuri $2;
root /var/www/DOCROOT/mass-username-sites/$username;
try_files /$newuri /index.html =404;
}

location ~ /m/(.*)$ {
rewrite ^(.*) $1/ last;
}

location ~ ^/s/(.*)/(.*)? {
set $userdomain $1;
set $newuri $2;
root /var/www/DOCROOT/mass-domain-sites/$userdomain;
try_files /$newuri /index.html =404;
}

location ~ /s/(.*)$ {
rewrite ^(.*) $1/ last;
}

Вот кусочек еггог-лога после включения дебага по запросу /m/test (на /m/test/anything та же реакция):


2012/04/23 09:12:28 [notice] 13702#0: *47 "^(.*)" matches "/m/test", client: X.X.X.X, server: domain.tld, request: "GET /m/test HTTP/1.1", host: "domain.tld"
2012/04/23 09:12:28 [notice] 13702#0: *47 rewritten data: "/m/test/", args: "", client: X.X.X.X, server: domain.tld, request: "GET /m/test HTTP/1.1", host: "domain.tld"
2012/04/23 09:12:28 [alert] 11927#0: worker process 13702 exited on signal 11 (core dumped)

От реального наличия и отсутствия директории указанной в root падение не зависит (падает все равно). В 1.1.18 работало. Вот бэктрейс:

Помогите, пожалуйста, разобраться, товарищи ученые. Не попробовать ли мне свежую ветку 1.2? Спасибо.
