I realized that zend_print_zval_r_ex dealt with the case of reference.

Description:
------------
zend_print_flat_zval_r and zend_print_zval_r_ex doesn't consider reference in php 7.0.x.

The following error may be triggered：
PHP Notice:  Array to string conversion;
Catchable fatal error: Object could not be converted to string.

This bug has been fixed in php 7.1, why php 7.0.x is not fixed.

Test script:
---------------
$a = array('a');
class b{};
$b = new b;
$test[] =& $a;
$test[] =& $b;
test($test);
function test() {
    debug_print_backtrace();
}


Expected result:
----------------
#0  test(Array ([0] => Array ([0] => a),[1] => b Object ())) called at
[/Users/playcrab/Documents/code/php/test/test7.php:7]

Actual result:
--------------
