Thank you for this bug report. To properly diagnose the problem, we

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.

Hello There !

PHP.
I am running lighttpd with php as fastcgi.
php crash time to time when it is compilde without --enable-debug.
I have busy site about 20 mln page views per day.
I have made a backtrace
Core was generated by `/usr/local/bin/php-cgi'.
Program terminated with signal 11, Segmentation fault.

The same script is working fine when php was compiled with
--enable-debug AND when user_id is filled not NULL then is NO crash
We have use Zend as framework so the code when
Reproduce code:
---------------
case 'votes':
$oVote = PS_Vote_UserProfile::factory(
PS_Auth::getInstance()->getProperty( 'user_id' ) );
and the function getProperty()
public function getProperty( $sName )
{
return $this->getUser()->$sName;
}
Actual result:
--------------
segfault
