VARCHAR2? That smells like Oracle...

I was able to reproduce this after replacing those VARCHAR2's with
VARCHAR. I added some debugging elog's (attached), and it looks like
libxml2 is trying xml_pfree a pointer we never gave it in any of the
alloc functions. Log attached, last xml_pfree crashes and it's the first
time 853c180 is mentioned.

I guess the next step is to narrow it down to a self-contained test case
and send a bug report to libxml people.
