This looks like another record issue: the code is accessing the
`services' field instead of the `name-service-switch' field, which is
right next to it.

So it looks like there are still stale .go files somewhere being picked
up.  This time it would mean that nss.go is up-to-date and system.go is
stale, since nss.go assumes an offset for `name-service-switch' that is
+1 compared to that of system.go.

Could you maybe try:

  rm -rf ~/.cache/guile
  make clean-go
  strace -f -o log make

and check in `log' whether .go files outside of the build tree are being
used?

Thanks,
Ludo'.
