I could reproduce the bug on WinXP Pro SP3, Win Server 2008 R2 and Win7 Pro.
Default Timezone: Europe/Berlin
Workaround with correct result:
date_default_timezone_set("UTC");
$start_timestamp = date_create('2012-06-01');
$end_timestamp = date_create('2012-12-01');
$difference = date_diff($start_timestamp, $end_timestamp);
var_dump($difference); //6 months
Could you reproduce the bug with:
date.timezone = "Europe/Berlin"
in php.ini on linux?

That output 06 on Linux

Description:
------------
The source code will return 05 instead of 06.
If you change the day to 02 instead of 01 in start_timestamp and end_timestamp
everything seems to work correct.
Debug:
print_r($start_timestamp);
Result: DateTime Object ( [date] => 2012-06-01 00:00:00 [timezone_type] => 3
[timezone] => Europe/Berlin )
print_r($end_timestamp);
Result: DateTime Object ( [date] => 2012-12-01 00:00:00 [timezone_type] => 3
[timezone] => Europe/Berlin )
Test script:
---------------
$start_timestamp = date_create('2012-06-01');
$end_timestamp = date_create('2012-12-01');
$difference = date_diff($start_timestamp, $end_timestamp);
$difference = $difference->format('%M');
Expected result:
----------------
06
Actual result:
--------------
05
