Sounds like a problem with linking against the stubs library...
but I don't much about Windoze... (thank heavens!)

You're supposed to reset the parser before parsing another
document.  Either that or destroy the old parser and create
a new, fresh one.

'::xml::parserclass info default' will tell you what is the
default parser.  That may help in tracking down the cause
of the problem.

Passing a NULL pointer sounds like a bug to me, and at the
very least the offending code should check that and deal with
it without crashing.  Please submit a bug report on SF,
including sample script, XML document and the patch that
you applied.
