[debug]> p /r m_Headers
[debug]$5 = (StringSet &) @0x116d0bc4: {_M_t = {_M_impl =
{<std::allocator<std::_Rb_tree_node<wxString> >> =

[debug]>>>>>>cb_gdb:

When I see the E:\code\gcc\PCXMinGW463\bin\libstdcxx\v6\printers.py, I see in
the line: 476
    def children (self):
        rep_type = find_type(self.val.type, '_Rep_type')
        node = find_type(rep_type, '_Link_type')
        node = node.strip_typedefs()
        return self._iter (RbtreeIterator (self.val), node)

The variable is declared as:  StringSet&              m_Headers;
and the StringSet is defined as: typedef std::set<wxString>  StringSet;

Hope those information can help to solve this bug.
