It's not really OS related. It's just the fact that your
broken code happend to work under Ubuntu for some reason.

You shouldn't even try to access r->variables by hand. Use
ngx_http_variables.[ch] functions instead.

If you know variable name at configuration stage, you should
probably use ngx_http_get_variable_index() during parsing config
and store returned index, and then use
ngx_http_get_indexed_variable() during request processing.

Multiple examples of variable usage may be found in various
official nginx modules, read source for details.
