PHP 7.3 Fatal error: Nesting level too deep - recursive dependency?

[gkopec]

After switching from PHP 7.2 to PHP 7.3 when I tried to add a bundle product to the cart I got this Fatal:
Fatal error: Nesting level too deep - recursive dependency? in /data/my/magento/app/code/core/Mage/Sales/Model/Quote/Item/Abstract.php on line 134

Possible solution is adding third parameter "true" to in_array function:

founded here:

This worked for me:
if (!in_array($this, $parentItem->getChildren(), true))

I am just wondering if Magento core is really ready for PHP 7.3...
