On ‘core-updates’ (e80514bc03b003a7ce95d7b55cf33c9f18f9e860) I get:

The difference between these two derivations is the build script. In
the second case, it reads this:

Notice the “kernel-headers” repetition, which is not in the correct
build script.
The repetition stems from the traversal done by ‘bag-transitive-inputs’,
which relies on pointer identity when comparing packages (via the ‘eq?’
vhash in ‘transitive-inputs’), and for some reason there are two non-eq?
linux-libre-headers packages encountered here. ‘master’ doesn’t have
this problem.
FTR we had a similar issue in http://bugs.gnu.org/20037 with PAM
services.
Incidentally, I discovered this bug while getting berlin.guixsd.org to
build ‘core-updates’: Cuirass there would exhibit the bug, and thus
berlin would end up building something different from what I have on my
laptop (and what hydra.gnu.org has.)
