Using this .gdbinit macro:

define plist
	set var $plist_iter=$arg0
	while ($plist_iter)
		if $argc==1
			print *$plist_iter
		else
			if $argc==2
				print $plist_iter->$arg1
			else
				print$arg2 $plist_iter->$arg1
			end
		end
		set var $plist_iter=$plist_iter->next
	end
end
document plist
List dumper iterating by `->next':
plist <head pointer> [<data field to display>] [/<format>]
end
