[SR-Users] CRITICAL ERROR in data_lamp.c!

[Mojtaba]

Not yet, because it is under developing, i could paste it here right away.

{
 .
 .
 .
    body.s = get_body(msg);
    if (body.s == 0) {
                LM_ERR("failed to get the message body\n");
        return -1;
    }
    body.len = msg->len - (int) (body.s - msg->buf);
//    body.len = strlen(body.s);
    if (body.len == 0) {
                LM_DBG("message body has zero length\n");
        return -1;
    }
    l = del_lump(msg, body.s - msg->buf, body.len, 0);
    if (!l) {
                LM_ERR("del_lump failed\n");
        return -1;
    }

    if (!insert_new_lump_after(l, newbody.s, newbody.len, 0)) {
                LM_ERR("insert_new_lump_after failed\n");
        return -1;
    }
}
I asked related issue in this regards in Kamailio developer forum,
before. let me paste it at below. The means of other_process function
is above code.
In during developing new module in Kamailio, I encountered with
strange behaviour. I used htable module instead of linked list for
save some temporary data during call process.dependencies module to
save some information. the skeleton of my code is like thus:

if (SIP_REQUEST &METHOD_INVITE) {
          insert_data_htable("some data");
          other_process(msg);
}else if(SIP_REPLY){
         get_data_htable("some data");
         other_process(msg);
}
In other_process function i have some changes in msg's body with message lump.
But after i make first call in kamailio. The kamailio was crashed.What
is it's problem?
In additional if i comment either insert/get_data_htable function or
othet_process function, i dont have this issue.
With best regards.
