Bug description:Segfault on get_defined_constants(TRUE)

Description:
------------
get_defined_constants(TRUE) started throwing me segfaults today, for
apparently no reason.  Worked yesterday, doesn't work today.  Test script
does only that function and still throws back no data.  I can't rule out
server configuration, but I have tested for it somewhat, with same
results.

Apache mod_php5 produces the segfault.  PHP CLI does not.

bug 15614 Had this problem with print_r(get_defined_constants(TRUE)) in
2002.  My segfault is happening with get_defined_constants(TRUE) alone.

Ubuntu 10.04

Linux 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:28:05 UTC 2010 x86_64


PHP 5.3.2-1ubuntu4 with Suhosin-Patch (built: Apr  9 2010 08:18:14) 

Zend Engine v2.3.0
    with Xdebug v2.0.5
    with Suhosin v0.9.29

Apache/2.2.14 (Ubuntu)


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

print_r(get_defined_constants(TRUE));

Expected result:
----------------
Function works.

Actual result:
--------------
[Mon May 10 15:08:44 2010] [notice] child pid 21884 exit signal
Segmentation fault (11)
