Subject: Module shutdown order again
From: rasmus@lerdorf.com (Rasmus Lerdorf)

Looking at https://bugs.php.net/bug.php?id=65463

My brain is foggy on why we call zend_destroy_modules() before
zend_hash_destroy(GLOBAL_CLASS_TABLE) in zend_shutdown(). Anyone
remember the reason?

I have verified the issue described in 65463. On a SIGTERM to Apache
mid-request, the extension ends up getting unloaded before the global
class table is destroyed causing the segfault described in the bug.
