Bug description:Crash due to dtor call happening after dtor shutdown
Description:
------------
If an object is created *after* the destructor shutdown, its dtor will be
called when it is freed, which potentially happens during a phase of the
shutdown process where the executor is no longer in a consistent state.
The test script uses the ob callback (called after dtor shutdown) to create
an object and bind it to to the error callback, which is later freed during
zend_deactivate, as part of the executor shutdown.
Result:
/home/nikic/dev/php-dev/Zend/zend_hash.c(946) : ht=0x42dea5c is already
destroyed
Test script:
---------------
<?php
ob_start(function() {
$foo = new Foo;
set_error_handler(function() use ($foo) {});
});
class Foo {
public function __destruct() {
var_dump($GLOBALS);
}
}
