            Bug ID: 59476
           Summary: gdb pretty-printer cannot print C++11
                    _Rb_tree_iterator
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: fdumont at gcc dot gnu.org

Since adaptation of std::_Rb_tree_iterator to conform to C++11 allocator
requirements there is no more _M_value_field member in _Rb_tree_iterator type
when compile with -std=c++11 option. In this context the pretty-printer script
should look for _M_storage member.
