Inside your addition to hostapd_interface_free(struct hostapd_iface *iface) you try freeing the afc channel and frequency arrays AFTER hostapd_cleanup_iface(iface), which contains an os_free(iface) call, which will then cause a dereference to a null pointer if accessed afterwards. Please move your #ifdef CONFIG_AFC section BEFORE the hostapd_cleanup_iface(iface) call and you should be fine.
