Looking around a bit, parse_str(), getimagesize() and preg_match() all do:
zend_get_parameters_ex(1, arg) zval_dtor(arg); array_init(arg);
These are broken too then?
Most probably. When you retrieve arguments with zend_get_parameters_ext() you are basically asking to receive it as read-only. You are allowed to use convert_to_type_ex() but you're not supposed to use functions which change the parameter directly such as convert_to_string(), zval_dtor() and so on.
