Description:
------------
Crash occurs randomly when accessing PHP scripts using Sun Java Enterprise Webserver 6.1 SP5.

In this case, I was using jmeter to generate some load and accessing a page containing 

<?
phpinfo()
?>

PHP was configured with: ./configure  --prefix=/opt/php --with-nsapi=/opt/SUNWwbsvr --enable-libgcc --enable-debug


Reproduce code:
---------------
<?
phpinfo()
?>

Expected result:
----------------
Standard phpinfo() response.

Actual result:
--------------
After a couple of hundred successful attempts, the webserver coredumps.
