What happens to an STL iterator after erasing it in VS, UNIX/Linux?

Question

Please consider the following scenario:

map(T,S*) & GetMap(); //Forward decleration

map(T, S*) T2pS = GetMap();

for(map(T, S*)::iterator it = T2pS.begin()         


        

Answer 1

I think if you modify the collection you invalidate your iterator. You can't rely on the behavior, as you found out.
