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.
