Issues with loading product collection after migrations + Magento 1.9.0.1

Question

I am encountering the following issue after migrating the Magento 1.9.0.1 website to a new server.

I am using a php script that I run using ssh which fetches all the products from database and create a csv. it worked fine on the original site but it throws error on the new server. Below is the error trace printed by magento.

The code that is throwing this error is this:

$products = Mage::getModel("catalog/product")
        ->getCollection()
        ->addAttributeToSort('created_at', 'DESC')
        ->addAttributeToSelect('*')
        ->load();

I couldn't figure out what the issue is. Any suggestions ?

I was using MariaDB 5.5, upgrading it to the latest version (10.1) sorted this issue. I am still not sure why the issue was caused but upgrade seemed to do the trick.
