>Description:
	If a netgroup is used in /etc/exports, and the netgroup is defined
as a NIS map (eg,   netgroup (,-,domain)   ) , then mountd will seg fault,
unless the hosts are specifically mentioned. (eg,    netgroup(host,-,-) )

>How-To-Repeat:
----------------------------------------
[/]cat /etc/netgroup 
netgroup (,,,)

[/]ypcat -k netgroup
netgroup (,,,)

[/]cat /etc/exports
/var/mail netgroup

[/]/usr/sbin/mountd 
Segmentation fault (core dumped)
----------------------------------------
[/]cat /etc/netgroup 
netgroup (localhost,,,)

[/]ypcat -k netgroup
netgroup (localhost,,,)

[/]cat /etc/exports
/var/mail netgroup

[/]/usr/sbin/mountd
