It seems that this fix caused a BC break from php 7.1.13. See the following gist on how to
reproduce: https://gist.github.com/andriesss/b22b4057bd7e0563f4d21b7b2cfd6a09

I also had this problem.
I am using Debian 9.1 and PHP 7.1.8.
Here is some sample code to reproduce the problem:
----------
class topClass
{
public $status;
public $baseRef;
}
class nestedClass1
{
public $statusDetail;
public $isSuccess = 1;
}
class nestedClass2
{
public $internalId = 1;
public $externalId = 3;
public $typeId = 10;
public $name;
}
$testObject = new topClass();
$testObject->status = new nestedClass1();
$testObject->baseRef = new nestedClass2();
$flatObject = new stdClass();
$iterator = new RecursiveIteratorIterator(
new RecursiveArrayIterator($testObject)
);
foreach ($iterator as $key => $value) {
$flatObject->$key = $value;
}
var_dump($flatObject);
----------
This is the result with the versions I tested.
PHP 5.2.17 and also 5.4.45:
object(stdClass)#99 (6) {
["statusDetail"]=>
NULL
["isSuccess"]=>
int(1)
["internalId"]=>
int(1)
["externalId"]=>
int(3)
["typeId"]=>
int(10)
["name"]=>
NULL
}
PHP 7.1.8:
object(stdClass)#99 (2) {
["status"]=>
object(nestedClass1)#97 (2) {
["statusDetail"]=>
NULL
["isSuccess"]=>
int(1)
}
["baseRef"]=>
object(nestedClass2)#98 (4) {
["internalId"]=>
int(1)
["externalId"]=>
int(3)
["typeId"]=>
int(10)
["name"]=>
NULL
}
}

Description:
------------
The problem I have observed is that in PHP7 and up RecursiveArrayIterator stops
iterating arrays that are object properties
However if I implement a class that has the exact same source code as RecursiveArrayIterator (taken
from here: http://fossies.org/dox/php-7.0.11-src/recursivearrayiterator_8inc_source.html)
and use that instead then object property arrays are iterated correctly.
