That is weird, cannot you reproduce it using the code below?

<?php
class main
{
    public static $dataAccessor;
}

class relay
{
    public function __get($name)
    {
		main::$dataAccessor = 1;
    }
}

main::$dataAccessor = new relay();
var_dump(main::$dataAccessor->bar);

?>

Anyway, please file a bug report: http://bugs.php.net/report.php

Thanks.
