Summary: segfault with large CALS table

Initial Comment:
I get a segfault without additional errors when trying to parse a large CALS table from a US patent document using XML::Twig which uses XML::Parser and expat underneath. I assume this may be the right buglist as a segfault should indicate the problem is (at least in effect) not on the perl side. libexpat is in version 1.5.2 (ubuntu 10.04). Attached is the offending table. There may be a problem in the xml itself, but usually that throws a meaningful parser error.

Message:
That's a very old version of Expat; a number of bugs have been fixed since
then.

Please try to reproduce with a current version of libexpat.
