Description:
------------
I downloaded 5.1 apc dll from snaps.php.net and installed it on my apache 1.3.33 / PHP5.1 cvs setup. It worked fine.
But, when it needs to cache a php file that has a class definition, apache crashes and no output sent.

I don't know how to trace it so i cant supply more information about crash.

Reproduce code:
---------------
Tried this: (works w/o class lines)

<?php
print_r(apc_cache_info());

class test
{
}
?>

Expected result:
----------------
Apc cache info

Actual result:
--------------
Apache crashes
