This is either bug in zend_fetch_list_dtor_id() as said in the 
    bug report or misuse of [zend_]register_list_destructors().
    
    So which one is it? Is zend_register_list_destructors() deprecated in
    favor of zend_register_list_destructors_ex() or what?? 

    FYI: register_list_destructors() is only used by ext/mssql in HEAD.
    It's also used by ext/crack in PHP_4_3. But not anywhere else.
    
    What's the difference between these two functions anyway??
    (some comments in the sources would be so nice sometimes :)

It seems to me that the difference is in the dtor() callback's parameters.
I'm not sure why type_name is not passed to 
zend_register_list_destructors(). It probably did not exist when it was 
originally written.
I guess we can either fix the comparison, change 
zend_register_list_destructors() to accept type_name, or nuke 
zend_register_list_destructors() completely and move to _ex().
Probably the last is the best option if we only have to fix two extensions.
