Description:
------------
PHP crush without any output after use array_unique with complex objects.
With php 5.1.6 all works ok. With primitive types all works ok.

Reproduce code:
---------------
  
echo '<br>Test1<br>';
var_dump($rel_list);
echo '<br>Test2<br>';
$rel_list=array_unique($rel_list);
echo '<br>Test3<br>';
var_dump($rel_list);
echo '<br>Test4<br>';


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

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

The problem is absence of __toString() method.
