[webkit-dev] Ever seen intermittent WebKit build errors like these?

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
