I've never seen that. Geoff On May 30, 2006, at 7:14 PM, Trey Matteson wrote:

I recently took a fresh pull of the WebKit repository, and when doing the initial build ran into all sort of weird, semi- reproducible errors (examples below). Often if I immediately retry the build, the same file will succeed, but then another similar weird error will crop up down the line. A few times the same file would persistently fail, but after a reboot the build would make progress. This is using Xcode 2.1 and 2.2.1, and I saw it on 10.4.2 and (mostly) 10.4.6. I even tried a fresh 10.4.6 install.

I'm curious if anyone else has ever run into similar errors building these projects.

It looks to me like some sort of hardware problem related to the disk storage, as if either the intermediate compiler products or the pages from the source files are getting corrupted (sometimes I get complaints about weird chars in the source). Along these lines, I tried switching hard disks, but saw the same issues. I tried both disks both internally and over Firewire, and FWIW this is a dual 1.25 GHz G4. On the other hand, I don't get any system hangs or panics, which would be more like other hardware problems I've had it the past. I don't really have any other odd symptoms besides these flakey WebKit builds.

Sorry that this is all somewhat tangential, but any related info would be appreciated, in case you've seen similar phantoms. Thanks, trey
