--- Comment #3 from anlauf at gcc dot gnu.org ---
The patch in comment#1 does not work for me on x86_64-pc-linux-gnu.
In decl.c:
6242 cleanup:
6243 if (saved_kind_expr)
6244 gfc_free_expr (saved_kind_expr);
6245 if (type_param_spec_list)
6246 gfc_free_actual_arglist (type_param_spec_list);
(gdb) p type_param_spec_list->expr->expr_type
$177 = 42350080
So type_param_spec_list really gets screwed up.
