In that case, your expectations of the getgrXXX functions are wrong.
The gr_mem field never returned all users belonging to a group.
Historically it only contains users for which this group is a
supplementary group, not a primary group.  It also doesn't make sense to
add all usernames to the gr_mem field of the "Users" group in companies
with thousands of employees, given that all users are member of the
group.
