The example says data structure should look like:

};
when omitting the last line "{ 0, NULL }"
wireshark crashes.
Yes, that's why the example says that - you need the last line there.
Does this last line have a ETX functionality ?
Yes. It's like the '\0' at the end of a C string, or the NULL "next"
pointer at the end of a singly-linked list, or like any of a number of
other data structures terminated with an end marker.
Shouldn't there be a better way to check the size/end of this data
structure!?
"Better" in what sense? Harder to omit?
