Sorry, the example was wrong ....
code :
void get_rpl_totag(struct cell *t, struct sip_msg *reply, str *totag) {
if (reply==FAKED_REPLY || !reply || !reply->to) {
tmb.t_get_reply_totag(t->uas.request, totag);
}
if (totag && totag->s) {
LM_ERR("reply_totag ok [%p][%d][%*.s]\n", totag->s,
totag->len, totag->len, totag->s);
}
}
...
str ttag = STR_NULL;
get_rpl_totag(t, reply, &ttag);
LM_ERR(">>> ttag[%p][%d][%.*s]\n", ttag.s, ttag.len, ttag.len,
ttag.s);
outputs :
0(25920) ERROR: acc [acc_logic.c:97]: get_rpl_totag(): reply_totag ok
[0x7f0559c2a1e0][41][ ]
0(25920) ERROR: acc [acc_logic.c:525]: on_missed(): >>>

I can not find the explanation on why the data memory
is different once I
return from the function.
This is the same process and the same memory address.
code :
void get_rpl_totag(struct cell *t, struct sip_msg *reply, str *totag) {
