I wanted to try and modify the elements of a bitmask for the purpose of dynamically changing the elements for a custom dissector. I used proto_tree_add_bitmask to kick off the process of building the proto_item (ti in my case). I found that I could access ti->first_child and manipulate the contents via proto_item_set_text. However, when I tried to access it->first_child->next I get segmentation faults, even if I check to see if it is NULL. I did some experimentation around ->next for proto_item and got consistent segmentation faults. Not the behaviour I was expecting, is this a bug or do I misunderstand the purpose of next in this context?
