I already asked multiple times but you don't answer: Show me where it says that. "Which is why MALLOC_CHECK is enabled in the RC". WHERE does it say that? How do you know that? Where did you read that?
Sorry, but the burden of proof lies with you. It was you who said that MALLOC_CHECK is erroneously enabled in the RC. Where's your source for that?
Ah then, it's official, release candidates shouldn't have the checks enabled.
Anybody else think that the KDE release process is a mess? The 4.6.4 tarballs contained 4.6.1 source (and other random stuff), now this. They needed a user to point out the issue! Maybe they should sit down, discuss and try to streamline things a bit.
