[sr-dev] [kamailio] kamailio 4.3 crash in update_dialog_vars_dbinfo (#301)

[Daniel-Constantin Mierla]

Interesting, it is clear the crash happened because the var pointer is invalid:

```
#0  0x00007f3b4fd779da in update_dialog_vars_dbinfo (cell=0x7f3b3c3aa958, var=0x3433) at dlg_db_handler.c:651
651     SET_STR_VALUE(values+2, var->key);
```

But it is taken from cell->vars, which show good values for each 'next' fields -- code of frame 1 is:

```
		for(var=cell->vars ; var ; var=var->next) {
			if (update_dialog_vars_dbinfo(cell, var) != 0)
				return -1;
		}
```

So the core file has some inaccurate info or the stack was corrupted. Did you get error messages in syslog before the crash?
