Bug description:fatal error with bad memory allocation in a script echo & exit

Description:
------------
Linux/CentOS 5.5 x86_64
PHP 5.3.4
Apache 2.2.16
Tested and can be reproduced under Apache httpd + mod_php5/nginx+fastcgi.
Ok under CLI(at least cant be reproduced under cli.)

I tested a script like below, which was simplified to the minimal.
I was about to dump something, then wrote a var_dump() with an exit;, then
i found the php results a fatal error like:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to
allocate 1702113144 bytes) in Unknown on line 0 ...

then In apache error log:

PHP Fatal error: Exception thrown without a stack frame in Unknown on line
0

Apache httpd/nginx usually gives *no response* to the http get request.


check the following code:
uncomment:
  1st __halt_compiler();   .... OK
  2nd __halt_compiler();   .... BAD

then exchange the lines of definitions of class a and b, uncomment:
  1st __halt_compiler();   .... OK
  2nd __halt_compiler();   .... OK


only in 5.3.4, works perfectly in 5.3.3.

Test script:
---------------
<?php
echo 'a';
exit;
#__halt_compiler();
class a extends b{}
class b{}

#__halt_compiler();
#new a;

Expected result:
----------------
a

Actual result:
--------------
error like
