include/ext/pb_ds/detail/pat_trie_/constructors_destructor_fn_imps.hpp
doesn't look right:


PB_DS_CLASS_T_DEC
typename PB_DS_CLASS_C_DEC::node_pointer
PB_DS_CLASS_C_DEC::
recursive_copy_node(const_node_pointer p_other_nd)
{
...
  size_type child_i = 0;
...
  --child_i; // What if child_i == 0?
  _GLIBCXX_DEBUG_ASSERT(child_i > 1);
