Right on the heels of the release of the PHP 5.1.0 Beta 1 today, Wez Furlong has a new post on his weblog about an issue already known with PDO.

Well, if you haven't tried it already, and you're interested in PDO, don't: just grab the latest snapshot from snaps instead. Lack of communication, and perhaps some politics, meant that 5.1beta shipped with a stupid bug in the PDO core extension, causing a infinite loop on request shutdown.

I'm somewhat annoyed at this, because it's a showstopper that we could and should have caught before announcing the beta. Oh well, such is life.

He doesn't mention what code might trigger it, so, if you plan on using (or getting into) PDO, be sure you get the latest from snaps.php.net...
