Can anyone spot the bug in following code from the tutorial [1]?

  PHP_FUNCTION(hello_dump)
  {
      zval *uservar;
  
      if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "z", uservar) == FAILURE) {
          RETURN_NULL();
      }

zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "z", &uservar

(it takes a ptr ptr)
