Tested it on 5.2-dev and 6.0-dev snapshots, incorrect behavior is same
on both.

Please try using this CVS snapshot:

  http://snaps.php.net/php5.2-latest.tar.gz
 
For Windows (zip):
 
  http://snaps.php.net/win32/php5.2-win32-latest.zip

For Windows (installer):

  http://snaps.php.net/win32/php5.2-win32-installer-latest.msi

Description:
------------
I don't know what to make of this behavior. When CURL creates a handle
with 32 characters or more to the local filesystem, duplicates it, and
then PHP attempts to create a new object while passing in a parameter
that is an array of values, PHP crashes. I could only produce this
behavior on Windows Vista.

Reproduce code:
---------------
<?php
// for Windows Vista, PHP 5.2.4
class foo { function __construct($var) {} }
curl_copy_handle(curl_init('12345678901234567890123456789012')); // 32
or longer
new foo(array('foo'));
echo 'Yay!';

Expected result:
----------------
Output of 'Yay!'

Actual result:
--------------
PHP aborts prematurely
