Could you post the code for your __get function? I think there are two
possible reasons for the discrepancy between 5.2.* and whatever version you
were running before:

1. You're using "Call-time pass-by-reference" by marking your return value
with an ampersand, try changing your code to this:

public function __get($field) {
  return &$this->_data[$field];
}

and removing the ampersand from the function call:

$a = $this->a;

or:

2. Perhaps the bug fix in 5.2.6 (see http://bugs.php.net/bug.php?id=43201)
changed the reference scheme.
