[boost] [property_tree] Issue: erase is corrupting the tree

I have following JSON structure loaded into boost::property_tree:
{
    "animals" : ["fox","dog","cat"]
}

I'm trying to delete the second item from the array by:
        auto assoc_it = loadedJSON.find("animals");
        auto it = loadedJSON.to_iterator(assoc_it);
        it = it->second.begin();
        it++; // move to second item
        loadedJSON.erase(it);

After this, when I try to use boost::property_tree::write_json to write the JSON back the app crashes. Do I use the property tree in a wrong way, or is there a bug?

Thanks,
Lukas.
