<?php
class Foo {
    function bar($str)
    {   
        return $str.'bar';
    }
}
function baz($str) {
    return $str."baz\n";
}
$foo = new Foo;
ob_start('baz');
ob_start(array(&$foo, 'bar'));
print 'foo';
?>

This script fails to add 'bar' to the string on every machine when
using PHP5, and it segfaults on mine.

foobarbaz
et@edea:~$ /usr/local/sources/unstable/php5-200305031330/sapi/cli/php

I know the config file path is odd, i just use the machine for
developing and i'm the only one working on it ;)
