Note: featureCode is initialized to NGX_CONF_UNSET_UINT, while
it's defined as ngx_int_t.
The NGX_CONF_UNSET_UINT macro is (ngx_uint_t) -1, that is, it's
maximum value representable in the ngx_uint_t type. Assigning it
to an ngx_int_t variable will result in integer overflow and the
behaviour is undefined. Depending on your C compiler and various
other factors this may or may not work (or may wipe your hard
disk).
Correct macro to use here is NGX_CONF_UNSET.
