Trying to build a distribution for 1.6_RC3 i build the toolchain and 
then went off with
	# ./build.sh -d -D /usr/destdir -R /usr/releasedir

After hours of computation build.sh end with a Segmentation fault:

	dependall ===> gnu/usr.bin/groff/man
	/usr/src/tools/obj/tools.NetBSD-1.6D-powerpc/bin/nbtbl

	/usr/src/tools/obj/tools.NetBSD-1.6D-powerpc/bin/nbgroff: troff: 
Segmentation fault 	(core dumped)
	*** Error code 2
	
	Stop.
	nbmake: stopped in /usr/src/gnu/usr.bin/groff/man
	*** Error code 1

This sounds bad. Does anybody have any idea what I could do?
