All active branches seem to reject this and don't ICE.

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::mapchar, Node*::iterator)
 auto next_son(mapchar, Node*::iterator it){
  ^
t.C:41:10: note:   no known conversion for argument 1 from ‘Node*’ to
‘std::mapchar, Node*::iterator {aka std::_Rb_tree_iteratorstd::pairconst
char, Node* }’

while 4.8 accepts it and later ICEs:

Please also provide the testcase with standard include for libstdc++, like

#include iostream


using std::vector;
using std::string;
using std::map;
...
