--- Comment #3 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Confirmed.
Currently unqualified_name_lookup_error makes a VAR_DECL for "undeclared_type".
Perhaps it should make an opaque type instead for this case?
519 /* Prevent repeated error messages by creating a VAR_DECL with
520 this NAME in the innermost block scope. */
521 if (local_bindings_p ())
522 {
523 tree decl = build_decl (loc, VAR_DECL, name,
error_mark_node);
524 TREE_USED (decl) = true;
525 pushdecl (decl);
526 }
The "fool" token at the "decl" gets consumed within
cp_parser_expression_statement here:
11225 statement = cp_parser_expression (parser);
11226 if (statement == error_mark_node
11227 && !cp_parser_uncommitted_to_tentative_parse_p (parser))
11228 {
11229 cp_parser_skip_to_end_of_block_or_statement (parser);
11230 return error_mark_node;
