The problem seems to be linked to the latest version (1.70) of XML::libXML ; a ticket was reported back in April 2010: https://rt.cpan.org/Public/Bug/Display.html?id=56671 Ville’s analysis of the problem has more details and ideas: http://lists.w3.org/Archives/Public/public-qa-dev/2010Jun/0002.html Doesn't seem like there is any easy way around that problem, thgouh 36097 1 ville.skytta 2010-06-10 22:24:52 +0000 Candidate fix in CVS: http://dev.w3.org/cvsweb/validator/httpd/cgi-bin/check.diff?r1=1.776&r2=1.777 55471 2 ville.skytta 2011-08-19 08:51:15 +0000 The mentioned fix as well as http://dvcs.w3.org/hg/markup-validator/rev/d32ff17ac5c8 have been in production since release 1.1 and have as far as I can tell worked around the problem satisfactorily so I'll mark this as resolved. Further, XML::LibXML development has been resuscitated recently and the root cause is supposedly fixed in >= 1.77.
