Yeah, I read up no gdb's list command and this seems wrong. I've downloaded the
kamailio source code via ```apt-get source``` and these are the lines around line 3060 in
pv_core.c:
```c
3050 hdr = msg->contact;
3051 while(hdr) {
3052 if (hdr->type == HDR_CONTACT_T) {
3053 if (!hdr->parsed && (parse_contact(hdr) < 0)) {
3054 LM_ERR("failed to parse Contact body\n");
3055 return pv_get_null(msg, param, res);
3056 }
3057 c = ((contact_body_t*)hdr->parsed)->contacts;
3058 while(c) {
3059 c = c->next;
3060 if(c->expires && c->expires->body.len) {
3061 if (str2int(&c->expires->body, &eval) < 0) {
3062 LM_ERR("failed to parse expires\n");
3063 return pv_get_null(msg, param, res);
3064 }
3065 efound = 1;
3066 if(eval>exp_max) exp_max = eval;
3067 if(eval<exp_min) exp_min = eval;
3068 } else if(msg->expires && msg->expires->parsed)
{
3069 eval = ehdr;
3070 efound = 1;
```
Shouldn't ```c = c->next``` be at the end of the ```while``` loop?
