Bug description:  Large-size PHP script crashes SunONE webserver

Description:
------------
When trying an PHP application (which uses generated code, some rather
quite large files) on Sun server running Solaris 8, the SunONE webserver
6.1 and PHP 4.3.4 using nsapi, one of the scripts crashed the server.

After some experimenting, it seems the size of the script file triggered
the crash: a PHP script > 128KB will bring down the server, a script <
128KB will not.

To complicate matters a bit, if a small script includes a large script,
the server will also crash, but if a small script will include two "half
size" scripts, it will not.

The server seems to run other PHP scripts well, and is also used to run
applets through its nsapi interface without problems.

PHP has been compiled as per instructions on the PHP website, with mysql
disabled, and ldap and oci8 enabled.



Reproduce code:
---------------
The test scripts consist of:

<?php
echo "hello";
exit;

$a = "123456789012345678901234567890123456789012345678901234567890";
// previous line copied till the script is large enough
?>

The scripts can be found at:

http://www.ozuzo.net/phpbug/test1.php.txt
=> WORKS
http://www.ozuzo.net/phpbug/test2.php.txt
=> CRASH

Include examples:

http://www.ozuzo.net/phpbug/test3.php.txt
=> WORKS
http://www.ozuzo.net/phpbug/test3a.php.txt
http://www.ozuzo.net/phpbug/test3b.php.txt

http://www.ozuzo.net/phpbug/test4.php.txt
=> CRASH
http://www.ozuzo.net/phpbug/test4a.php.txt

Expected result:
----------------
The word "hello".

Actual result:
--------------
The server crashes with the following message (no entry in the PHP log):

failure (25268): CORE3107: Child process closed admin channel
fine (25268): CORE3061: signal_handler_thread: received signal 18
