The subject says it all. Here is a "sctrace" of the lpd process
where the forked lpd dumps core and the dbx of the stack. I suspect
this bug has to do with the old inettgr bug that most vendors never
fixed after they got their hands on the original ONC sources (Sun and
HP, BTW, have fixed this). Replacing the netgroup with host entries
fixes the problem. I will do it that way, but I am disappointed to
another in a long list of bugs.
