Hard to see what it could have done to cp. ;-)

Off hand I would think this can only be eu-strip's fault.
Unless something is silently touching files in the build
or something, then it looks like eu-strip run twice
(nondestructively) on the same input file produced
differing stripped files.
Rawhide has elfutils-0.132, which is also in updates-testing
for F-[78]. If it's handy, you could try a kernel build on a
rawhide with elfutils downgraded and see if that fixes it, or
try a build on F-8 and see if it's broken by upgrading to the
new elfutils from updates-testing.
I still haven't fired up the ol' G5 to look into the thing
with the vmlinux copies going into the wrong debuginfo rpms.
So when I get it together, I can look into this too.
I have to do a new rawhide install and such first though.
Thanks,
Roland
