Yes, I just recompiled again and the timestamp is updated on opcache.so. But like I said removing
that extension from php.ini to disable it has no effect, so it's not hanging because of any
extension I've defined there.

However, I am seeing these warnings when compiling now. Not sure what to do about them:
/usr/bin/ld: warning: libssl.so.10, needed by /usr/lib64/libssh2.so.1, may conflict with
libssl.so.1.0.0

Well, just check the timestamp

The only extension in my php.ini is
zend_extension = "opcache.so"

I was under the impression that this recompiles in tandem with every PHP recompile, as I've
never actually compiled that module manually.

I suppose this could matter if you have shared extensions that you didn't recompile after that
change since the order changed in that Bucket struct. Check that all your .so extensions were
compiled against this new struct layout.

Finally narrowed it down to a single commit.

This was the breaking change: http://git.php.net/?p=php-src.git;a=commitdiff;h=76019b86c0ede959e000c164b02ed8b1d8bb29e1

I'm not sure why that matters, but I think that change needs to be rolled back, or it at least
needs to be investigated why it causes returns of object instances stored as local static array
entries to sometimes hang.
