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 keeping
the former working as before.

	PR plugins/108634
	* 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.
