Description:
------------
After using apc_store and apc_fetch to store variables total size of variables stored goes negative, guessing the datatype used is wrapping.

Reproduce code:
---------------
http://www.tequilasolutions.com/apc.gif
http://www.tequilasolutions.com/apc2.gif

Expected result:
----------------
Correct total of bytes reported.

Actual result:
--------------
Negative total of bytes reported, probably overflowing the datatype used.  Lots of fragmentation start as soon as you use the apc_store() function.  Not sure if this is anything to worry about.

Using latest APC.  Don't know if others are affected, but probably..

There where a number of type size bugs, I'm not sure if it's the same as this bug or not.  Could you please upgrade and verify if this is still an issue?  If it is do you have a way to consistently reproduce?
 [2008-03-17 04:59 UTC] apc at tequilasolutions dot com 
I've not seen it recently, dont know how to reproduce and I am using the latest version so might as well close this?
 [2008-03-23 22:00 UTC] shire@php.net 
Yeah, I'll close this for now, but if you see it again please just re-open this or make a new bug for me.  thanks.
