Comment 2 Jan Pokorný [poki] 2019-12-09 14:30:23 UTC

Note that this wouldn't be an issue if assumed invariants on how
libxml2's data structures always held.  Alas, that appears broken in
XML::LibXSLT Perl module for years -- problem that wasn't exposed
until this v2.9.10 release.

Applying this patch won't make the problem in the Perl module go away,
but at least it will mask it again sufficiently enough to prevent,
e.g., Publican segfaults.

That being said, I've also filed a mirror copy of an upstream report
for XML::LibXSLT, https://rt.cpan.org/Public/Bug/Display.html?id=131146,
[bug  1781205].
