I had code like this:
$user = new eZUser( $session->variable("AuthenticatedUser" ) );

And I noticed now that this creates a segfault in php.

The workaround is changing the code to:

$val = $session->variable( "AuthenticatedUser" );
$user = new eZUser( $val );


The code worked with php-4.0.3pl1 and has worked with 
4.0.4, but it's reproduceable and I think it's a PHP bug.

The eZSession::variable() function returns a string value.

I've tested it with 4.0.4pl1 and the bug is still there.
