--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. The testcase is rejected with GCC 4.9+ with
.C: In member function ‘void Trie_tree::dfs(Out, Node*)’:
t.C:146:50: error: no matching function for call to ‘Node::next_son(Node*&)’
for (; son != NULL; son = (root->next_son(son))->second) {
^
t.C:146:50: note: candidate is:
t.C:41:10: note: auto Node::next_son(std::map<char, Node*>::iterator)
auto next_son(map<char, Node*>::iterator it){
^
t.C:41:10: note: no known conversion for argument 1 from ‘Node*’ to
‘std::map<char, Node*>::iterator {aka std::_Rb_tree_iterator<std::pair<const
char, Node*> >}’
while 4.8 accepts it and later ICEs:
