Works for me under 2.3.2 (with expat 1.95.6) and 2.4.1 (with
expat 1.95.8).

Try upgrading your expat and see if the problem goes away.

I can reproduce on Linux with current CVS and expat
1.95.5-2.  Note the size of the data only needs to be
greater than 1024.

xml = "<?xml version='1.0' encoding='iso8859'?><s>%s</s>" %
('a' * 1025)

I am not certain this problem is specific to Python.  It
might be down in expat only.  Need to investigate further.
