Memory leak suspicion in wap-appl.c

Hi, list.
I suspect memory leak in wap-appl.c
It's about set_referer_url():

static void set_referer_url(Octstr *url, WSPMachine *sm)
{
         gw_assert(url != NULL);
         gw_assert(sm != NULL);

     sm->referer_url = octstr_duplicate(url);
}

In wap-appl.c we use it:

             if (session_id != -1) {
                 debug("wap.wsp.http",0,"WSP: Setting Referer URL to <%s>",
                       octstr_get_cstr(url));
                 if ((sm = find_session_machine_by_id(session_id)) != NULL) {
                     set_referer_url(url, sm);
                 } else {
                     error(0,"WSP: Failed to find session machine for ID %ld",
                           session_id);
                 }
             }

I don't see where preovious sm->referer_url destroyed.
Must we before
sm->referer_url = octstr_duplicate(url);
Insert
octstr_destroy(sm->referer_url); ?

Or may be I simply didn't find where it destroyed ;-) .
