Description:
------------
Crash when using DateTimeZone object, previously returned by
DateTime::getTimezone()


This worked fine in PHP 5.2.5
Probably this is related to how DateTimeZone object is returned:

This code returns different results in 5.2.5 and 5.2.6

$old_tz = $d->getTimezone();
$d->setTimezone(new DateTimeZone('UTC'));
echo $old_tz->getName();

5.2.6 returns 'UTC', while 5.2.5 returns 'Asia/Novosibirsk' (my current
timezone). Having in mind how objects in PHP5 are returned, I can accept
this, but this must be documented properly and shouldn't cause crash.

Reproduce code:
---------------
$d = new DateTime();
$old_tz = $d->getTimezone();
$d->setTimezone(new DateTimeZone('UTC'));
// setDate() and setTime() may go here - just for this example to make
some sense
$d->setTimezone($old_tz);
echo "Success";

Expected result:
----------------
Success

Actual result:
--------------
PHP interpreter crashes
