I see no evidence of Perl CORE causing trouble. All that happened
was a method was called on a undefined value. My experience tells
me that this is an incompatiblity between MARC::File::SAX and
XML::LibXML::SAX and MARC::File::XML, or else a bug in the first.

Also, my experience with XML parsing in Perl (and Koha) has been
less than "calming" due to the multiple implementations of XML
parsing from CPAN, multiple incompatible C libraries (libxml*) that
do that parsing and the interactions of C-based XML parsing and
the native Perl parser. Methinks the problems in that bug report
might be related to that.

Why would you deduce that it is the Perl CORE at fault? I have been
using Perl since 1995 and have *never* encountered incompatibilities
going forward.
