I have that Sun-3/150 running NetBSD/sun3.  (Pretty much vanilla 1.1.)

I was logged in, running window, and had a kernel build going in one
window (well, the build was running >& a file, with less +F on that
file running in the window).  In another window I started a "make
World" to build X11R6.  Just a few moments after starting the second
make, it died, and at about the same time the kernel build died.  The X
build died with

	making imake with BOOTSTRAPCFLAGS=-Dsun3
	cc -o ccimake -Dsun3 -O -I../../include ccimake.c
	cc: Internal compiler error: program cc1 got fatal signal 4
	*** Error code 1
[and the usual cascade of "Stop."s]

and at the same time, the kernel build died with 

	cc -Werror -msoft-float -O -I. -I../.. -I../../../../arch -I../../../../sys -I../../../.. -DNEWCONFIG -DMACHINE_NONCONTIG -DTIMEZONE="0" -DDST="0" -DGENERIC -DFPU_EMULATE -DHAVECACHE -DSWAPPAGER -DVNODEPAGER -DDEVPAGER -DKTRACE -DDDB -DNFSSERVER -DNFSCLIENT -DFFS -DCD9660 -DFDESC -DFIFO -DKERNFS -DNULLFS -DPROCFS -DUNION -DINET -DNFS_BOOT_RWSIZE="0x400" -DCOMPAT_SUNOS -DCOMPAT_09 -DCOMPAT_10 -DCOMPAT_43 -DTCP_COMPAT_42 -DDIAGNOSTIC -DSCSIDEBUG -D_KERNEL -Dmc68020 -Dsun3  -c ../../../../arch/sun3/sun3/machdep.c
	cc: Internal compiler error: program cc1 got fatal signal 10
	*** Error code 1

4 is SIGILL, 10 is SIGBUS.  I restarted the kernel build and it is now
(several files later) chugging happily along, as far as I can tell.  I
didn't restart the X build (yet).

Anyone have any idea what happened here?  In particular, is it serious?
