Description Zdenek Dohnal 2020-04-09 06:21:20 UTC 
Hi,

I have to tell at the start - I'm not sure whether it is issue of glibc, but make/xargs binaries (where segfaults seem to origin) are compiled with glibc, so maybe just they need to be fixed... but I rather file it on glibc first, because it was the only updated package between successful build and the failed one (at least in Vim) which IMO can cause the similar segfaults.

The several builds failed only on i686/armv7hl:

Vim - segfaults on make:
https://kojipkgs.fedoraproject.org//work/tasks/8185/43148185/build.log

flocq - segfaults on remake:
https://kojipkgs.fedoraproject.org//work/tasks/5608/43145608/build.log

nip2 - segfaults on configure:
https://kojipkgs.fedoraproject.org//work/tasks/2414/43142414/build.log

rust-proc-macro-error - segfaults on xargs:
https://kojipkgs.fedoraproject.org//work/tasks/2854/43142854/build.log

podman - segfaults on xargs:
https://kojipkgs.fedoraproject.org//work/tasks/2661/43142661/build.log

lmod - segfaults on xargs:
https://kojipkgs.fedoraproject.org//work/tasks/4155/43144155/build.log

Would you mind looking into the issue?

In the meantime, I'm running:

$ koji tag f33-pending glibc-2.31.9000-6.fc33
Created task 43153881
Watching tasks (this may be safely interrupted)...
43153881 tagBuild (noarch): free
43153881 tagBuild (noarch): free -> closed
  0 free  0 open  1 done  0 failed

43153881 tagBuild (noarch) completed successfully


However I'm never sure if this is enough.

Comment 3 Miro Hrončok 2020-04-09 08:22:57 UTC 
With glibc-2.31.9000-6.fc33 back in the buildroot, the problem seem to be gone (for now).
Comment 4 Florian Weimer 2020-04-09 15:58:55 UTC 
The make failure looks like this (only happens with -jN if more than one target is built):

==46== Invalid write of size 4

This was reported on libc-alpha: https://sourceware.org/pipermail/libc-alpha/2020-April/112547.html

A fix is under review:

https://sourceware.org/pipermail/libc-alpha/2020-April/112574.html
https://sourceware.org/pipermail/libc-alpha/2020-April/112596.html

The patch needs a v3.
Comment 5 Florian Weimer 2020-04-14 16:37:28 UTC 
Fix was pushed upstream: https://sourceware.org/git/?p=glibc.git;a=commitdiff;h=00515ea3a15703a3d196c1d1bd372214abc990ad

So we a good to rebase glibc past this bug.

I'm seeing this again as well.

I'm deeply sorry about this, I had a momentary lapse of judgement.
