Yep, this happens with the Brazil/East time zone, so it's just crossing a DST
boundary: if you look at $interval->h on the last interval, it's 23 hours from
midnight on the 21st to midnight on the 22nd and therefore not a full day.

Unable to reproduce here as well with PHP 5.3.10. Which timezone are you using?
Most likely DST-related.

Obviously some wretched daylight savings issue. Call:
date_default_timezone_set('UTC');
It's the only way to make any programming language's date handling sane.

I couldnt reproduce the problem, I get a result of 1 on:
$a = new DateTime('2012-10-21');
$b = new DateTime('2012-10-22');
$interval = $a->diff($b);
Tested Ubuntu 11 64 bits also

Description:
------------
The diff function is calculating the wrong number of days.

Test script:
---------------
<html><head><title>TEST</title></head><body>
<?php
$a = new DateTime('2012-10-19');
$b = new DateTime('2012-10-22');
$interval = $a->diff($b);
?>
<p>$interval->days:<?=$interval->days?></p>
<?php
$a = new DateTime('2012-10-20');
$b = new DateTime('2012-10-22');
$interval = $a->diff($b);
?>
<p>$interval->days:<?=$interval->days?></p>
<?php
$a = new DateTime('2012-10-21');
$b = new DateTime('2012-10-22');
$interval = $a->diff($b);

<p>$interval->days:<?=$interval->days?></p>
</body></html>
Expected result:
----------------
$interval->days:3
$interval->days:2
$interval->days:1

$interval->days:2
$interval->days:0
