The problem is quite >> simple, I did some debugging and got a segfault in zend_variables.c:61 ZEND_OBJ_HT_P(zvalue)->del_ref(zavlue TSRMLS_CC); seems that the class definitions an extension defines are lost (the extension is unloaded) before the created variables are destroyed. object_handlers table is destroyed. If you set your object to null inside php script or if you destroy all public variables inside module shutdown sequence it works fine... $a=null; works fine. code block from php_request_shutdown() (main.c:1216) if (PG(modules_activated)) { zend_deactivate_modules(TSRMLS_C); // modules are unloaded } [...] zend_deactivate(TSRMLS_C); // variables are destroyed inside here If you change the order it works and there are no segfaults. but there are some other problems php reports: /home/mepeisen/projects/php/php-5.0.0b3/Zend/zend_hash.c(672) : ht=0x8230ef8 is already destroyed /home/mepeisen/projects/php/php-5.0.0b3/Zend/zend_hash.c(672) : ht=0x8230ef8 is already destroyed /home/mepeisen/projects/php/php-5.0.0b3/Zend/zend_hash.c(67) : Bailed out without a bailout address!
