getpwent and groups

[Daniel Ellard]

I use NIS to manage passwords, and due to a
policy change I recently changed the last line
of the password file from

	+:::::::::

to

	+ at ellard-guest:::::::::

so that only my "guests" are able to log in to my machines instead of
everyone in the entire department.

This works fine as far as logins are concerned.  The problem is that
now programs that use getpwent (i.e.  finger and top) now seg fault!

Is this a known problem, and if so is there a fix in the works?

I'm running 4.8p15.

Thanks,
