freebsd stable - Jan 2004 - RELENG_4 -> RELENG_4_9 sidegrade problem?

I decided to drop back to 4.9 after running 4-STABLE for a while, and,
after doing that, I removed the gettext port, and then rebuilt all of
gnome and kde.  The weird thing is that samba-devel would not build -
it failed in different places with a signal 10.

Jan 23 20:07:09 netcom1 /kernel: pid 49412 (cc1), uid 0: exited on signal 10
Jan 23 20:11:48 netcom1 /kernel: pid 64708 (cc1), uid 0: exited on signal 10
Jan 23 20:19:19 netcom1 /kernel: pid 78970 (cc1), uid 0: exited on signal 10
Jan 23 20:23:42 netcom1 /kernel: pid 92596 (cc1), uid 0: exited on signal 10
Jan 23 20:38:05 netcom1 /kernel: pid 9992 (cc1), uid 0: exited on signal 10

This system has been stable for months, and after going back to
RELENG_4 samba built no problem.

Any problem with either

- 4.9 or
- "sidegrading" like this?

It's possible that there are some leftover files, of course, that
caused this, but I don't know what they would be.

I had signal 10 problems last year around June, and mouse problems
after that, but I think they were BIOS related and I haven't seen
either for months.

Anyone have any clues/ideas?

I am using the cursed VIA/AMD combo, which took a lot of BIOS tweaking
to get working well, but it seems stable once dialed in.

Actually, I was having problems around June 2003 (same problem, signal
10 in cc1) so it's possible that there is code around this date in
-stable that got into 4.9 and was later fixed.  I'll just keep running
RELENG_4 for now, it seems rock-solid.  I am just running a few jails
now so I would rather have a more "stable" system, release-wise.
