This did not happen with x86_64 or s390x for instance.

Comment 1 Jan Pokorný [poki] 2019-11-26 20:49:11 UTC

This is reproducible, see
https://koji.fedoraproject.org/koji/taskinfo?taskID=39370020
or submit a (scratch) build for pacemaker from koji,
hash 5d2275ed5a21fb031fb3c919673c2a8945c876c3
> 2.0.3-1 (rev. 3) - Fix unability to build with Inkscape 1.0 beta
on your own.

This blocks Pacemaker update in Fedora [bug 1776552].

Comment 2 Jan Pokorný [poki] 2019-11-26 20:56:11 UTC

armv7hl architecture appears to suffer from the same problem.

Comment 3 Jeff Fearn 🐞 2019-11-27 00:44:37 UTC

This is most likely due to some lib publican is using not working on those arches. At a guess I'd say it's most likely libxml or expat. You would need to check the core dump to be sure.

Comment 4 Jan Pokorný [poki] 2019-11-27 08:35:28 UTC

Note that consequently, publican itself is now FTBFS on those archs

Comment 5 Ben Cotton 2019-11-27 14:20:45 UTC

Fedora 29 changed to end-of-life (EOL) status on 2019-11-26. Fedora 29 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

Comment 6 Jan Pokorný [poki] 2019-11-27 14:34:15 UTC

Thank you, buggy automation.

Comment 7 Jeff Fearn 🐞 2019-11-29 04:47:51 UTC

I have this in mock:

Aborted (core dumped)

There is no core though, so unsure what that is related to ATM.

Comment 8 Jeff Fearn 🐞 2019-11-29 04:58:07 UTC

It looks like libxml2 and libxslt have been rebuilt for rawhide but perl-XML-LibXML and perl-XML-LibXSLT have not, so maybe that is the problem.

Comment 9 Jeff Fearn 🐞 2019-11-29 05:23:56 UTC

GDB trace, haven't worked out how to et debuginfo's in mock yet though.

some missing or crazy initialization going on):

Comment 11 Jan Pokorný [poki] 2019-12-05 23:27:50 UTC

Clear culprit here is an update from libxml2-2.9.9-7.fc32.i686
(works fine) to libxml2-2.9.10-1.fc32.

Vaguely aiming at a location match, this might be the culprit:

Jeff, if anything, please see a more in-depth assessment
https://gitlab.gnome.org/GNOME/libxml2/issues/132#note_663698
whether there's anything actionable in your powers.

Comment 15 Jan Pokorný [poki] 2019-12-06 16:10:07 UTC

There's also https://rt.cpan.org/Public/Bug/Display.html?id=131146

Comment 16 Jeff Fearn 🐞 2019-12-07 00:21:04 UTC

Hi Jan, I don't think Publican has any "extensions functions", XML::LibXSLT is used by many perl modules and is not part of Publican.

https://metacpan.org/requires/module/XML::LibXSLT?sort=[[2,1]]

Comment 17 Jan Pokorný [poki] 2019-12-09 14:35:38 UTC

Also filed a mirror copy of an upstream report for XML::LibXSLT,
https://rt.cpan.org/Public/Bug/Display.html?id=131146, [bug  1781205].

That seems the proper way to address the root cause.
