I'm not really following the details, but is this useful to you?

Yes, it means that the reported error is not an artefact of the Haskell "unix" package, but rather originates directly from normal use of the getpwnam_r(3) glibc API on these systems. It would now be useful to also post: - The output of "./g root" or some other group known to exist. - The output of "./g xyzzy" or some other short group name known to not exist - The output of "grep group /etc/nsswitch.conf" - Attach an strace output file (g.trace.txt) from: strace -o g.trace.txt ./g -- Viktor.
