Nanode | Arduino examples for the Nanode

I'm using a map template called ITV with a defined struct as key value and a set of pairs of integers as map value. For any reason the insert command simply doesn't work for some key value.

I have reduced my code to the smallest possible, but it is still large. It can be compiled and executed, and returns one line whenever one pair is added to the map value of some domain, indicating the key value and the size of the associated map value at that time.

Unfortunately, at some point of the function intervals() (at case initial arc) the insert command does nothing:

ITV[Domain(PairStr,q)].insert(make_pair(t,t)); // ERROR! DOES NOT WORK

I guess this may be related to some internal ordering of the map class, because the error is made only whenever the PairStr is ("INI", "A"), the only case with PairStr.first > PairStr.second, but I really don't have any idea about this.
