Trevor Saunders <tsaunders at mozilla dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |tsaunders at mozilla dot com --- Comment #2 from Trevor Saunders <tsaunders at mozilla dot com> --- So we went from find_slot taking a const uninon tree_node *& to taking a union tree_node * const& I tend to think that the later is more "correct" since the type of thing in the hash table and hence the thing that is const is a union tree_node *. Further the result of find_slot is a tree_node ** which is not const. So I think the appropriate solution is to just const_cast to tree, but a sanity check of that would be nice.
