Argh, you are right. This problem will still be present as long as you use the old PCRE version. The fix only affects installation and upgrade, that is what I actually mean. If you tried installing a version with the fix on an old PCRE version, then MediaWiki would just not allow installation. This is the way this fix works; it does not actually solve your problem. The error will stay.
