Segfault nginx 1.1.19

[mikevmk]

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

2012/04/23 09:12:28 [alert] 11927#0: worker process 13702 exited on

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.
