class-simplepie.php error php 5.4

Deprecated: Assigning the return value of new by reference is deprecated in /wp/wp-includes/class-simplepie.php on line 738

Replacing every =& with =
a fatal error kicks in:

$this->data = $this->data[‘child’][end($this->namespace)][end($this->element)][];

line 14567

Back to the deprecated errors, but hoping for a fix in the next version
