I am hand patching zend.c for each version I upgrade or else I experience php code crashing the
Apache instance. I did add feedback, but it was ignored.

$DDB = new AmazonDynamoDB();
$DDB->use_ssl = false;
$Key = array('HashKeyElement' => array(AmazonDynamoDB::TYPE_NUMBER =>
(string)$itemid));
$Res = $DDB->get_item(array('TableName' => 'pond_item_meta',
'Key' => $Key));
$tt = (string)$Res->body->Item->exif_json->S;
But this is the offending code. Casting on a CFSimpleXML object. Worked flawlessly to 5.4.7. Is it a
CFSimpleXML bug?

seems it's a recursively call to __toString..
like:
<?php
class A {
public function __toString() {
return (string)$this;
}
}
so I think this should not considered as a bug... but a wrong usage
