[sr-dev] [kamailio/kamailio] Kamailio Random Crash Alert - 5.4.7 (Issue #3186)

[sagarmalam]

It is crashing because current->mname is NULL. I dont know how it could be NULL but will try to figure it out. 

Suggestion : 
I think we should check if current->mname is not NULL before strcmp for protection from crash 

```
static int rpc_mod_is_printed_one(mem_counter *stats, mem_counter *current) {
	mem_counter *iter = stats;

	while (iter && iter != current) {
		if (strcmp(iter->mname, current->mname) == 0) {
			return 1;
		}
		iter = iter->next;
	}

	return 0;
}
```

@miconda Can you please help me with some direction to debug this issue ? And do you agree with my suggestion to add protection ?
