I found another bug.
xml_call_handler() causes...but I think it is different my first report.

reproduce code:
  <?php
  class Handler {
      public function startElement() { }
      public function endElement() { }
  }
  $parser = xml_parser_create();
  $handler = new Handler();
  xml_set_element_handler($parser, array($handler, "startElement"), array($handler, "endElement"));
  xml_parse($parser, "<?xml version=\"1.0\"?><root />", true) OR
      die(xml_error_string(xml_get_error_code($parser)));
  xml_parser_free($parser);
  ?>

actual:
