Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

$a =& $foo[]; 

Where =& means that both $a and $foo[<next index>] should point to 
same place, and in your example they both point to null so:

var_dump($a, $foo);

Outputs:

NULL
array(1) {
  [0]=>
  &NULL
}

Description:
------------
Using array-operator to access a non-existing key of a referenced
variable turns variables that are false or an empty string into arrays.

Reproduce code:
---------------
<?
$abc = false; // or ''
var_dump($abc);
$a = &$abc['unsetKey'];
var_dump($abc);
?>

Expected result:
----------------
Warning: Cannot use a scalar value as an array

Actual result:
--------------
boolean false

array
  'unsetKey' => null
