The following test code runs fine the first 29 (your mileage may vary) times the page is viewed. On the 30th time, CPU usage shoots to 100% briefly and Apache 2 crashes hard.

'30' is the magic number for my system, I imagine your mileage may vary if this is - as I suspect - some sort of memory corruption bug.

The problem appears to be with the exception handling mechanism, since I can comment all the code out, or attempt to refresh the page 50+ times with a class declaration / simple method call.

Reproduce code:

try {
	throw new Exception( 'Testing' );
catch( Exception $e ) {
	echo $e->getMessage();


Expected result:
'Testing' should appear on screen.

Actual result:
For the first 29 times the page is viewed, 'Testing' appears. On the 30th time, Apache 2 crashes hard.

5.0.0RC1 still has this bug - my mileage is "6"

You need to use Netscape to test this - IE will not ask the server to reexecute the code
