System: NetBSD pizza.causeuse.org 8.0_BETA NetBSD 8.0_BETA (BLACKBOX-$Revision: 1.85 $) #0: Mon Sep 25 20:23:42 CEST 2017 hauke%pizza.causeuse.org@localhost:/var/obj/netbsd-builds/8/amd64/sys/arch/amd64/compile/BLACKBOX amd64

>Description:

	While cross-building a custom i386 kernel on an amd64 machine,
	config(8) busy-loops, then eventually dumps core.

% /u3/netbsd-builds/8/i386/tools/bin/nbconfig -v -v TP380D

	written successfully (it is the only file in conf/TP380D/):
