I posted this in the Xcode 3.2 thread, probably not the best place: So I'm brand new to C programming, and I've been following the "Masters of the Void" tutorial series. So far, it's been working pretty well; however, sometimes I'll hit 'tab' a couple of times on my keyboard to indent a line in a few times (to match the example), and Xcode gives me the following error: One tab/indent usually works, but the second will bring up this error. Hitting continue will just bring me back to Xcode (where the error will repeat if I hit tab), and hitting quit will exit Xcode. I googled the error message, and the only thing I could find was about a font overload on 10.3 (w/ safari, mail, etc). Any idea what could be causing the problem? Useful info: Macbook, 4gb RAM, 2.4ghz c2d, 250gb hd OS X 10.6 Xcode 3.2 I was going to submit an error to radar.apple.com, but after putting in my email/password, the site gives me an error.
