Bug #15254 Updated: modules are unloaded in the wrong order

ID: 15254 Updated by: hholzgra Reported By: stephensb@aciworldwide.com Status: Open Bug Type: Reproducible crash Operating System: Linux, Solaris and win32 PHP Version: 4.1.1 New Comment: i remember doing something about that somewhere around 4.0.5, too, but i can't remember the outcome :( Previous Comments: ------------------------------------------------------------------------ [2002-01-28 08:14:22] stephensb@aciworldwide.com zend_hash_destroy destroys things in order. Thus, if one has two loadable modules, one of which depends on the other by calling a function in the initialization or finalization functions, then bad things will happen whichever order they appear in php.ini, since whichever way around they're listed, a function will be called after the providing library has been unloaded. Our fix is simply to change zend_hash_destroy to traverse its list backwards (from ht->pListTail rather than ht->pListHead). (I believe we (probably as MessagingDirect) reported this bug in PHP3 and it was fixed then, but it seems to have reappeared.) ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=15254&edit=1
