    As I said earlier, I think it is better to tweak gdbhooks.

    The following patch does that, I've tested it now both with gcc 12 and
    older gcc as system compiler and the patch fixed the latter while keepi=
ng
    the former working as before.

            * gdbhooks.py (TreePrinter.to_string): Wrap
            gdb.parse_and_eval('tree_code_type') in a try block, parse
            and eval 'tree_code_type_tmpl<0>::tree_code_type' instead if it
            raises exception.  Update comments for the recent tree_code_type
            changes.=
