'gcc -da nothing.c' crashed because execute_todo does:

       if (properties & PROP_trees)
         dump_function_to_file (current_function_decl,
                                dump_file, dump_flags);
       else if (properties & PROP_cfg)
         print_rtl_with_bb (dump_file, get_insns ());
       else
         print_rtl (dump_file, get_insns ());

and get_insns() is not available yet, we do not have RTL.
