Subject:   Yoics! Just upgraded and cc is (mostly) bus-error-ing on buildworld.

Just to prefix with my config:
FreeBSD duncan.reilly.home 9.0-CURRENT FreeBSD 9.0-CURRENT #7: Sat May 29 11:20:54 EST 2010     root@duncan.reilly.home:/nb/obj/nb/src/sys/DUNCAN  amd64
Current source tree was csupped about half an hour ago.

I don't think that my hardware has gone dodgy: everything else
seems to be working properly. cc itself seems to work OK when
compiling my own code, too.  But make buildworld -->

/nb/src/cddl/usr.bin/sgsmsg/../../../sys/cddl/contrib/opensolaris/common/avl/avl.c:128: internal compiler error: Bus error: 10
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html>; for instructions.
*** Error code 1

Stop in /nb/src/cddl/usr.bin/sgsmsg.

Also, if I run buildworld with -j4 (my usual config), then a
different compile crashes the same way :

/nb/src/cddl/usr.bin/sgsmsg/../../../cddl/contrib/opensolaris/cmd/sgs/tools/common/string_table.c:467: internal compiler
error: Bus error: 10

but in that case it was not the first compile which broke, and
several (parallel, I assume) broke at the same time.

So: is anyone else seeing this?

Is it likely that heisenbugs have found their way into the compiler in the last week, or perhaps in the kernel's page table
handling code?

More importantly: any thoughts about how I can proceed from
here?  Re-install from a snapshot?

Cheers,
