Segmentation Fault when using find() or creating instance of model

[dfsoeten]

I'm trying to setup MongoDB using this package and it's ODM. Currently everything seems to work except the instantiation of models extending the \Phalcon\Mvc\MongoCollection class.

My services.php:

use Phalcon\Db\Adapter\MongoDB\Client as MongoClient;
use Phalcon\Mvc\Collection\Manager;

//MongoDB Database
$di->set('mongo', function () {
    $mongo = new MongoClient('mongodb://' . getenv('MONGODB_HOST') . ':' . getenv('MONGODB_PORT'));

    return $mongo->selectDatabase(getenv('MONGODB_NAME'));
});

//Collection Manager
$di->set('collectionManager', function () {
    return new Manager();
});

My Pages.php model:

class Pages extends \Phalcon\Mvc\MongoCollection
{
    public function getSource(){
        return 'pages';
    }
}

When I try to do the following, my page results in a The connection was reset error and child pid <id> exit signal Segmentation fault (11) notice in the Apache logs:

$pages = new Pages();

OR

Pages::find();

However, I can do $mongo->listDatabases() and get the following result:

object(Phalcon\Db\Adapter\MongoDB\Model\DatabaseInfoLegacyIterator)#167 (1) { ["databases":"Phalcon\Db\Adapter\MongoDB\Model\DatabaseInfoLegacyIterator":private]=> array(2) { [0]=> array(3) { ["name"]=> string(5) "admin" ["sizeOnDisk"]=> float(49152) ["empty"]=> bool(false) } [1]=> array(3) { ["name"]=> string(5) "local" ["sizeOnDisk"]=> float(32768) ["empty"]=> bool(false) } } } 

The MongoDB PHP Driver also seems to work:

$collection = (new Client('mongodb://' . getenv('MONGODB_HOST') . ':' . getenv('MONGODB_PORT')))->danqcms->pages;
$collection->find()->toArray();

Phalcon 3.4.2 isn't compatible with PHP 7.3.
V4 for is but still in alpha and the mongo support is still part of a discussion here

Wasn't quite sure if my current setup was supported due to the message on the top of the page found here. Thanks.

EDIT: I've managed to fix the issue by downgrading to PHP 7.2!

Phalcon 3.4.3 is now available for PHP 7.3, so this might get re-opened again
