With LAST_UPDATED: "Sun Nov 28 09:51:57 UTC 2004" I get:

With the message in the .log for all being:
*** EXIT code 4242
(a call to abort)

Note that reporting these as one is not a presumption that
these regressions are all due to the same cause, though I will
split this PR only if I later find that's not the case.  The
specific number of MMIX regressions didn't seem to be of general
help, so I'm not doing that extra work anymore, I'm just
logging regressions.

Last known to work on: "Tue Nov 23 17:37:12 UTC 2004".
Known to fail on: "Thu Nov 25 02:57:33 UTC 2004"
with patches to fix PR target/18331, where named patches found 
not to cause this or any regression on an earlier checkout.
