/**
 * There seems to be an issue in PHP itself that i can only replicate 
 * under Ubuntu 20.04 and running through phpunit. It results in a 
 * segmentation fault in the zend_declare_typed_property function. 
 * The error does not occur when no custom "create_object" function is asssigned
 * simutaneously with property declarations. So i rewrite the obj parser to 
 * hold a "resource" object containing the fast_obj data.
