Bug #75942 [NEW]: Backward incompatibility introduced in RecursiveArrayIterator

From: andries at centim dot be Operating system: any PHP version: 7.1.14 Package: SPL related Bug Type: Bug Bug description:Backward incompatibility introduced in RecursiveArrayIterator Description: ------------ I'm referencing to ticket https://bugs.php.net/bug.php?id=73209 that was fixed in PHP 7.1.14, and seems to have introduced a backward compatibility issue compared to PHP 7.1.13. I'm creating a new ticket, as this ticket was already closed. When RecursiveArrayIterator is used in combination with a RecursiveIteratorIterator, and your class has a public property that contains a DateTime instance, it will crash with the following error: Overloaded object of type DateTime is not compatible with RecursiveArrayIterator This did not produce an error on PHP 7.1.13, Was it a bug that it didn't iterate object properties? Or is supporting it a new feature? I lean toward the latter without having seen the spec, but either way the current fix breaks backward compatibility.
