Comment 1 Andrew Pinski 2004-08-05 06:35:57 UTC

I have not have problems on powerpc-apple-darwin on a dual 2.5GHz G5 with -j5 unless this is new.

Comment 2 Andrew Pinski 2004-08-05 06:45:40 UTC

*** Bug 16847 has been marked as a duplicate of this bug. ***

Comment 3 H.J. Lu 2004-08-05 07:09:46 UTC

It may depend on the kernel scheduler. I only see that failure under certain
kernels. I don't know Java enough to figure out the dependencies between
different files.

Comment 4 Andrew Pinski 2004-08-05 18:19:12 UTC

I see this now on powerpc-apple-darwin so there must have been something which just changed:

Comment 5 Bryce McKinlay 2004-08-05 18:56:38 UTC

I've seen this before when doing incremental rebuilds. I don't think it is a
parallel build problem, but rather a compiler bug that occurs when it gets a
certain combination of class vs java files during the build. Doing a clean
rebuild has always fixed it for me. Next time I see it in my tree, I will try
and debug.

Comment 6 Andrew Pinski 2004-08-05 18:59:57 UTC

I got it with a clean "make -j5 bootstrap".

Comment 7 H.J. Lu 2004-08-05 20:26:08 UTC

Created attachment 6888 [details]
A patch

I agree that it is a compiler bug. At least, it shouldn't lead to
segfault. In the meantime, I have been testing this patch. I haven't
seen a failure in several runs.

Comment 8 H.J. Lu 2004-08-05 20:30:54 UTC

BTW, I don't think you can easily debug it since it only happens
for parallel build. When I ran the failed command by hand, I never
got a failure. I don't know how to control other compile processes,
which triggers the bug.

Comment 9 Bryce McKinlay 2004-08-06 15:18:39 UTC

I've seen it before when doing an incremental build, eg non-clean build after
"cvs update", even without parallel make. But I can imagine how parallel builds
could also cause it.

Comment 10 Bryce McKinlay 2004-08-13 20:55:26 UTC

HJ, are you still seeing this bug? I do parallel builds of libjava several times
a day on 4-way machines and have not seen this bug for at least 2 weeks.

Comment 11 Andrew Pinski 2004-08-13 21:44:40 UTC

I still see it, like today.

Comment 12 H.J. Lu 2004-08-13 23:04:16 UTC

Like most of parallel build bugs, it may not be reproduced easily and reliably.
I don't want to be tied up by this bug. Since I applied my patch, all my builds
have been OK.

Comment 13 Andrew Pinski 2004-09-12 01:37:02 UTC

I can no longer reproduce this, I think the patch for PR 17290 fixed the issue of getting dependencies 
right so we no longer get wrong dependencies and make would not make the wrong discussion.

Comment 14 Bryce McKinlay 2004-09-13 22:21:01 UTC

Well, this bug was not caused by wrong dependencies, but rather a compiler bug.
So, I don't see how it could be fixed. But, I agree with your decision to close
it without an easy to reproduce test case.

Comment 15 H.J. Lu 2004-09-15 16:26:24 UTC

It happened again with mainline at Tue Sep 14 23:08:41 UTC 2004

Comment 16 Mark Mitchell 2005-01-19 18:52:09 UTC

Ada and Java bugs are not release-critical; therefore, I've removed the target
milsetone.

Comment 17 Andrew Pinski 2005-01-19 19:32:15 UTC

I just to be able to reproduce this all the time too but lately (in the last two months) I have not been 
able to so closing as fixed.
