SIGSEGV в ngx_create_full_path()

[Victor Antonovich]

Всем привет!

Имеем: nginx 0.7.67 на Centos 5.5 i386.

После добавления в конфиг WEBDAV-location'а:

location /obr {
   allow 127.0.0.1;
   allow 192.168.1.0/24;
   deny all;
   alias /usr/local/cruisecontrol/data/m2/repository;
   dav_methods PUT DELETE MKCOL COPY MOVE;
   create_full_put_path on;
   dav_access group:rw all:r;
}

в error.log'е стали появляться сообщения:

2010/08/18 17:41:18 [alert] 9744#0: worker process 9746 exited on signal

Проблема наблюдается и на версии 0.6.39.

Это баг или фича? В принципе, с виду все работает, файлы создаются и 
изменяются, но такое поведение мне что-то не нравится.

Всем спасибо!
Виктор.
