--- Comment #1 from Paolo Carlini paolo.carlini at oracle dot com ---
In our case the issue is slightly different, the problem is in
cp_parser_initializer_list, here:

  cp_parser_parse_tentatively (parser);
  cp_lexer_consume_token (parser-lexer);
  designator = cp_parser_constant_expression (parser, true, non_const);
  cp_parser_require (parser, CPP_CLOSE_SQUARE, RT_CLOSE_SQUARE);
  cp_parser_require (parser, CPP_EQ, RT_EQ);
  if (!cp_parser_parse_definitely (parser))
designator = NULL_TREE;
  else if (non_const)
require_potential_rvalue_constant_expression (designator);

where cp_parser_constant_expression is tentatively called. I think it can be
solved by looking forward for the '=', similarly to other GNU extensions, for
example compound literals.
