Bug description:'use()' array reference crashes PHP - zend_hash.c

Description:
------------
This problem doesn't occur to 5.3.3 (my usual development environment) but
the latest stable and snaps, tested on both 32-bit and 64-bit machine
(Ubuntu Hardy and Lenny)

$ ~/opt/bin/php -v
PHP 5.3.6 (cli) (built: Mar 31 2011 16:04:07) (DEBUG)

$ ../opt/bin/php -v
PHP 5.3.7-dev (cli) (built: Apr  1 2011 00:15:05) (DEBUG)

The program will exit with return code 0 - which is the annoying part.


Test script:
---------------
<?php

function m(&$a){
  $b = &$a;
  call_user_func(function() use($b){});
}

function n($a){
  call_user_func(function() use($a){});
}

$a = array('a');

n($a);
m($a);

exit;


Expected result:
----------------
[Thread debugging using libthread_db enabled]
/home/yclian/Development/src/php5.3-201103311430/Zend/zend_hash.c(520) :
ht=0x8924f6c is inconsistent

Program exited normally.
(gdb) quit


Actual result:
--------------
Do not fail.
