Like I said in the bug report, install APC from SVN. We have a few more
things to fix before we are ready for an APC release. Unfortunately
there are a lot fewer people working on APC than other parts of PHP. It
is extremely difficult and not very sexy work. And with that enticing
description, if anyone reading this would like to pitch in and help fix
the remaining small PHP 5.4 edge cases in APC, it would be much appreciated.
