The problem isn't with classes. Just a simple "valgrind php" show the
errors.

I reproduced in 5.3 (CVS), the problem is occuring with all classes.
(not only internal)

Description:
------------
PHP 5.2.5 and current snapshot (php5.2-200801291330) cause a crash when
extending an internal class and terminating the script with die(); or
fatal error.

This does no happen with debug build or with USE_ZEND_ALLOC=0

Reproduce code:
---------------
class a extends arrayobject 
{
} 
die();

Expected result:
----------------
No output

Actual result:
--------------
/opt/php5-cvs/bin/php -r 'class a extends arrayobject {} die();'
zend_mm_heap corrupted
