>Description:
I was doing a complete (except X) build of NetBSD currentm
when that finishes, I use the tools it constructed, to compile
my local kernels (for reasons not important here, I don't
use build.sh for that). The kernels that build correctly
were fine. But one of them I have a config problem with
(have had for a while - the link fails - undefined symbols - why
is also not important right now).
Immediately after the link failed make printed the very
long command line it had been executing, said "*** Error code 1".
"Stop." and "nbmake: stopped in ..." all of which was normal.
Then it dumped core (seg fault).
Traceback:
Core was generated by `nbmake'.
Program terminated with signal 11, Segmentation fault.

Since this was a normal tools build, there ar eno debug symbols,
but I could re-build make with -g, and run it again if the
problem doesn't turn out to be obvious.
This is new in the past day or so.
>How-To-Repeat:
Probably not easy - or it might be. Perhaps purposely mis-configure
a kernel in a way that "config" doesn't object to, and see what
happens, or perhaps config a kernel, then edit the Makefile and
remove one of the object files from the list, so linking cannot
possibly work. It is only because I don't really need a new Dom0
kernel anytime soon that I had been ignoring the link error on my
past few (well, more than a few) builds...
