This is indeed a bug. I've just committed a patch to the git repository:
https://github.com/chaoslawful/lua-nginx-module/commit/d577a38
Please try out ngx_lua v0.5.12rc1 on your side:
https://github.com/chaoslawful/lua-nginx-module/tags/
or you can just try out the latest prerelease of ngx_openresty that
already includes this version of ngx_lua:
http://agentzh.org/misc/nginx/ngx_openresty-1.2.1.11rc1.tar.gz
BTW, I've cc'd the openresty mailing list:
http://groups.google.com/group/openresty You're very welcome to join
there too :)
Thanks!
