Segfault with midgard_datetime properties

[bergie]

Using a database with some https://github.com/nemein/fi_openkeidas_diary/blob/master/models/challenge.xml entries populated:

<?php
// Open a connection
$filepath = ini_get("midgard.configuration_file");
$config = new midgard_config();
$config->read_file_at_path($filepath);

function connect($config) {
    $mgd = midgard_connection::get_instance();
    return $mgd->open_config($config);
}

if (!connect($config))
{
    die("Failed to connect\n");
}

$qb = new midgard_query_builder('fi_openkeidas_diary_challenge');
var_dump($qb->execute());

Results in:

        Segmentation fault

Segmentation fault happens because of recursive output of classes. object has reference to datetime, which has it's private member "object" pointing back to class, etc.

Fixing this would mean "hiding" object-pointer in midgard_datetime class

do not reinit datetime objects in get_properties(). this helps to keep var_dump() happy. Closed by ac15ac160f46ac05f52c46a6cb1850392d64ca3d
