I also can reproduce this error (Suhosin Patch installed). Very simple
test script:
<?php
$demo_user[]=(object)array("first" => 1);
$demo_user[]=(object)array("second" => 2);
$demo_user[]=(object)array("third" => 3);
echo "<pre>"; var_dump($demo_user); echo "</pre>";
?>
Error Log:

I am having this same issue on Ubuntu 8.10 running against Sybase 12.5.
This actually just started happening against the CLI version of PHP when
attempting to connect more than once to the database server in the same
request. Any idea when this might get fixed? Or if not, anyone have a
reliable work around?

This solution I saw on another website might help fixing it in a next
build of PHP or at least show people with the same problem a way out of
it:
