regression failure in CVS HEAD
About 1 in every 5 runs of the (parallel) regression tests are failing
for me with CVS HEAD: the triggers, inherit, vacuum, sanity_check, and
misc tests fail. I can make the failures occur fairly consistently by
running "make check" over and over again until the problem crops up.
The platform is Linux 2.4, gcc 3.2. I've attached the regression.diffs
file.
Any ideas on what the cause might be?
Cheers,
Neil

Hardware?
If it's a software bug, you'd generally expect it to happen each and
every time...

It could be an order dependency in a parallel group.
The sequential runs don't throw a periodic error do they?

Yipes. I have not been running the parallel tests (my habit is to run
make installcheck, instead) but there is clearly something busted.
I got a bunch of failures similar to yours in my first attempt with
make check on HPUX --- see attached.
Any ideas on what the cause might be?
No. Can anyone offer data on when this started?

I see passes on March 2nd, updated and see passes today.
Did 5 runs of make check on today source.

I've spent the morning trying to reproduce this, without success. After
a "make maintainer-clean", cvs update, full rebuild cycle, I cannot get
anything funny to happen in "make check" under HPUX, RH Linux 8.0, or
OS X.
I'm a bit hesitant to write it off as a build problem, because
(a) I can't see anything in the recent CVS logs that might cause such,
and (b) it's surprising that it'd bite both you and me. But at this
point I don't see what else to say.
Can you still reproduce the problem after a clean rebuild?

FWIW, I just updated to cvs tip, did
make clean
./configure ...
make all
make install
make check (repeated 6 times)
The only failure I get is horology due to the
"--enable-integer-datetimes" issue (which I think there is a patch in
the queue for). This is on Red Hat 7.3.

No -- I ran "cvs update", "make clean", followed by 10 runs of the
regression tests but I didn't get any similar failures.
I suppose we can just regard it as a build problem, then? Not sure what
the actual culprit was, though...
Cheers,
Neil

I'm mystified too. But unless we see it again, I think we have to write
it off as a build error.
Do you use --enable-depend when configuring? I don't, so I know that
I take some risk of build errors when I do things wrong.

Yeah, I did -- which I why when I reported it initially I assumed that a
build problem wasn't the cause.

Hm. One of the reasons I don't use --enable-depend is that I don't
trust it ;-) --- I prefer to do a make clean and rebuild after every
cvs update.
It's disturbing that we both saw similar failures, when there's no
obvious explanation for a build problem in the CVS logs. I have a
sneaking feeling that we haven't seen the last of this issue. But with
no ability to reproduce it, there's not much point in worrying now.
