Fix: 

not known.
How-To-Repeat: 
Set up configuration files as above.  Attempt to rlogin from a host in
cshosts1 (any host?).

This bug has been fixed with the last revision of getnetgrent.c. The 
problem is that the code will try to fclose /etc/netgroup without actually 
having fopened it in the case where /etc/netgroup doesn't exist. 
(fclose(NULL) ==> SIGSEGV) 

There is a simple workaround which is to create an /etc/netgroup file 
that is empty (touch /etc/netgroup) or that has only a single plus 
sign ('+') in it.
