If you think you spot a bug, You'd better open a ticket on Trac
https://trac.nginx.org/.

You could also talk about development matters on the nginx-devel
http://mailman.nginx.org/mailman/listinfo/nginx-devel Mailling List. This
is the 'users' ML, centered on use cases/configuration/help
with/discussions around the software.
