Description

Because nginx_version is not casted to unsinged integer,
nginx does not output the correct version.

nginx: [emerg] module "/usr/local/nginx/modules/ngx_http_hello_world_module.so" version 1009012 instead of 140166258713971 in /usr/local/nginx/conf/nginx.conf:13

The following patch fixes the issue.

IMO, it's better to adjust specifier instead:
