running).

Unfortunately the python package also fails with equivalent test 
failures. It also has another failure mode where it expects a syscall to 
change ownership to the overflow uid to result in EPERM, while it will 
produce EINVAL (which happens even if there are no supplementary 
groups). Should I post the details here or open a new issue?

coreutils already responded and fixed the issue 
(https://debbugs.gnu.org/cgi/bugreport.cgi?bug=78225).

I still have to report to gnulib, but wanted to try building the 
standalone gnulib package first, which caused me to trip over the python 
issues.
