New Revision: 4815
URL: http://trac.nginx.org/nginx/changeset/4815/nginx

Log:
Map: fixed optimization of variables as values.

Previous code incorrectly used ctx->var_values as an array of pointers to
ngx_http_variable_value_t, but the array contains structures, not pointers.
Additionally, ctx->var_values inspection failed to properly set var on
match.
