I can't reproduce this using 5.3 from today:
bjori@jessica:/usr/src/php/5.3$ sapi/cli/php t.php 
PHP Warning:  Invalid argument supplied for foreach() in
/usr/src/php/5.3/t.php on line 12

Output with reduced test script:

# src/build/php_5_2/sapi/cli/php t.php
Segmentation fault
# src/build/php_5_3/sapi/cli/php t.php
Segmentation fault
# src/build/php_6/sapi/cli/php t.php

Warning: Invalid argument supplied for foreach() in /home/jani/t.php on
line 12

So it seems the bug is only in PHP_5* branches.

reduced test case

<?php
$data = array (
        'level0' => array(
        'level1'
        )
    );

$flattened = flatten($data);

function flatten($data, $separator = array()) {
    extract($separator, EXTR_OVERWRITE);
    foreach ($data as $key => $val) {
            flatten($val, array('separator' => $separator));
    }
}

?>
