  Summary:
  - Build reliably fails on LP
  - Build in local sbuild works reliably on my Laptop
  - Build in local VM (sizing like LP builders) works (other crashes but works)
  - Build on AMD server (chip more similar to LP) works reliably

  Failing step:

  On Launchpad build infrastructure it breaks on ld:

  Summary:
  - Build reliably fails on LP
  - Build in local sbuild works reliably on my Laptop
  - Build in local VM (sizing like LP builders) works (other crashes but works)
  - Build on AMD server (chip more similar to LP) works reliably

  Failing step:

  On Launchpad build infrastructure it breaks on ld:

  Summary:
  - Build reliably fails on LP

  - Build in local VM (sizing like LP builders) works (other crashes but works)
  - Build on AMD server (chip more similar to LP) works reliably

[Touch-packages] [Bug 1958389] Re: Jammy builds of xen segfault, but only on launchpad x86 builders

[Christian Ehrhardt ]

For xen itself we know now how to "work around it" which is retry until running 
on one of the new builders. Leaving the bug open as it clearly seems to be a 
real issue.
I also leave the PPA as-is so that you can grab sources from there for 
recreating this binutils issue.

[Touch-packages] [Bug 1958389] Re: Jammy builds of xen segfault, but only on launchpad x86 builders

[Christian Ehrhardt ]

Being a platform dependent (thereby rather severe, but easy to miss)
crash in binutils I feel it is time to bump priority of this to get it
onto the radar avoiding to ship it that way (potentially breaking more)
in our next LTS.

** Changed in: binutils (Ubuntu)
   Importance: Undecided => Critical

[Christian Ehrhardt ]

This build ran 10:26 -> 10:33 and the crash happened "in between". As i
said in local sbuild those are not fatal but on LP they are. Therefore
attaching the build log ...

** Attachment added: "build log that did not exit fatally, but triggered the 
crash we also see on LP (there fatally)"

[Christian Ehrhardt ]

Thanks for the hint,
in case anyone needs to do the same - you can see the associated builder right 
when the build starts - then abort it immediately, refresh and rebuild.
That way you get 1 build try <1min, I got

lgw01 018
lgw01 044
lgw01 023
lcy02 001

And the build on the latter I let finish which indeed let it build
successfully.


That also means the crash I got locally is actually relevant to doko or anyone 
else looking for this from binutils POV. Therefore I'll attach mine.

[Touch-packages] [Bug 1958389] Re: Jammy builds of xen segfault, but only on launchpad x86 builders

[Christian Ehrhardt ]

Thanks Colin, even without debug symbols that still is probably enough
to confirm it is actually the same crash that I see on my laptop.

While I do not see why it is fatal for the build on LP but not on local
sbuild or dpkg-buildpkg in a local VM it means that most likely someone
looking into this from the binutils POV can reproduce it the way I
outlined in my report on most common intel laptops.

In use here I have:
Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz

Maybe you could add what chip the failing lgw01 builders use to try
isolating the affected series?


/me is trying to retry until it ran on an lcy02 builder now ...

[Touch-packages] [Bug 1958389] Re: Jammy builds of xen segfault, but only on launchpad x86 builders

[Colin Watson]

I've tested manually on a staging lcy02 builder and it works fine there,
so worst case you should be able to retry until it happens to land on
lcy02.

I've reproduced the problem on a staging lgw01 builder.  I need ddebs to
get a useful backtrace, so I've filed
https://code.launchpad.net/~cjwatson/canonical-is-
firewalls/+git/firewall-configs/+merge/414372 to get access to those
from the relevant builder - I should be able to pick this up again once
that's merged.

[Touch-packages] [Bug 1958389] Re: Jammy builds of xen segfault, but only on launchpad x86 builders

[Christian Ehrhardt ]

Hi Colin,
so far I've seen it only on lgw01, but I didn't mass-submit it yet to try the 
other builders.
Is there a better way than re-building/re-submitting to get onto the lcy02?

[Colin Watson]

Both the failures linked here were on lgw01.  Have you seen this on
lcy02 as well, or only lgw01?

  Summary:
  - Build reliably fails on LP
  - Build in local sbuild works reliably on my Laptop
  - Build in local VM (sizing like LP builders) works (other crashes but works)
  - Build on AMD server (chip more similar to LP) works reliably

  Failing step:

  On Launchpad build infrastructure it breaks on ld:

[Touch-packages] [Bug 1958389] Re: Jammy builds of xen segfault, but only on launchpad x86 builders

[Christian Ehrhardt ]

FYI: I've seen some shortening of the reported crashes going on.
For example in journal it was "x86_64-linux-gn" and in the build log it was 
after "x86_64-linux-gnu-ld". The local (non fatal) crash I got eventually was 
in "x86_64-linux-gnu-ld.bfd".

This might or might not be the same crash on LP and locally, but as I
mentioned above one fails critically the other one is ignored.

Could someone run that build manually on LP and/or stop it before
cleanup to gather the crash from there for comparison?
