Hi,
this low priority ICE on invalid happens only in c++98 mode but I think
we can as well avoid it and have consistent error recovery across std
modes. Essentially, the VAR_DECL for 'b' with erroneous TREE_TYPE (the
type is incomplete) reaches cxx_eval_constant_expression and we ICE when
we use COMPLETE_TYPE_P on the TREE_TYPE itself. I think we can -
consistently across std modes - catch the erroneous type quite a bit
earlier, midway in finish_case_label, thus before the case_conversion
call which eventually leads to the ICE. Tested x86_64-linux.
ok
