-----------------------------------------------------------------
Hi!

I get an segmention fault using HTML::Parser just when it calls XSLoader::load("HTML::Parser", $VERSION).


perl -e 'use HTML::Parser;'

results in a segfault:


Signal SEGV at /usr/lib/perl5/site_perl/HTML/Parser.pm line 17.
    require HTML/Parser.pm called at ./test.pl line 4
        main::BEGIN() called at /usr/lib/perl5/site_perl/HTML/Parser.pm line 0
            eval {...} called at /usr/lib/perl5/site_perl/HTML/Parser.pm line 0
            Aborted (core dumped)

The affected line HTML/Parser.pm:17 is:
XSLoader::load('HTML::Parser', $VERSION);



perl -v:
This is perl 5, version 20, subversion 0 (v5.20.0) built for x86_64-linux-thread-multi
(pacman says 5.20.0-5)



HTML::Parser is installed through the AUR (Arch Linux) and is on version 3.71-3


please contact me if I got anything wrong (not entirely sure if this should be posted here or rather as a HTML::Parser bug report) or you need more information.

Sincerely, Andrew.
