Description:
------------
When running 2 or more requests simultaneously on my 850 MHz laptop, including "class MyException extends Exception{}" to a simple Hello World script causes Apache to crash randomly.

The setup is a stand alone 850 MHz laptop running Windows 2000, Apache/1.3.34, PHP/5.1.1, and Apache's JMeter.  Apache is configured with ThreadsPerChild = 50 and PHP loaded as a module (LoadModule php5_module c:/php/php5apache.dll). 

Launching Apache's JMeter, I accessed the test script using single or multiple threads, no timing pauses, and enough loops to drive the CPU load to 100% (e.g., 1 thread/600 loops, 2 threads/300 loops, and 30 threads/20 loops).

Reproduce code:
---------------
<?php

class MyException extends Exception {
}

print("Hello World\n");

?>


Expected result:
----------------
Script should run without problem when accessed using 1 or multiple threads.

Actual result:
--------------
Running single threaded access, there were no problems.  When accessed using multiple threads, there were consistent random failures of Apache.  For example, usually see around 7 crashes while running 600 requests with 30 threads. 

Dr. Watson reports them as Exception number: c0000005 (access violation) or occasionally Exception number: 000006a6 ().

Removing "class MyException extends Exception{}" from the script eliminated the multi-thread crashing problem.  All thread settings (1, 2 & 30) would run to completion without problems.
