Description:
------------
I'm intermittently getting these warnings in my php logs:

[11-Aug-2010 09:54:24] PHP Warning:  Unknown: GC cache entry '/home/xxxx/public_html/include/settings.php' (dev=26625 ino=0) was on gc-list for 4657081 seconds in Unknown on line 0

[11-Aug-2010 09:54:24] PHP Warning:  Unknown: GC cache entry '/home/xxxx/public_html/include/utils.php' (dev=26625 ino=0) was on gc-list for 4664290 seconds in Unknown on line 0

It seems to have happened since I upgraded to PHP 5.3.3 and APC 3.1.4 (I did a pear upgrade after updating PHP).

Expected result:

I expected not to see any warnings

Since APC 3.1.4, Error message logging from stderr to php error.

sometime, apc error message is not need.

I think maybe allow user set error logging to stderr OR php error pipe, just sample:

apc.error_output = STDERR|PHP_LOG

apc 3.1.4 change ref to: http://pecl.php.net/bugs/bug.php?id=17527

According to <https://bugs.php.net/69618>, APC support has been
discontinued in favor of OPcache, APCu, the session upload
progress API and WinCache. Therefore this issue won't get fixed.
