Status: VERIFIED FIXED

'Nother assert...  This one while viewing http://sagan.earthspace.net/~esr/ecsl/

Line 541 of pa_parse.c:

pa_DocData *
PA_DropDocData(NET_StreamClass *stream)
{
    pa_DocData *doc_data=(pa_DocData *)stream->data_object;
    XP_ASSERT(doc_data &&
/* >> */     (doc_data->stream_count >= 1));
    if (!doc_data)
	return NULL;
    doc_data->stream_count--;
    return pa_check_doc_data_count(stream);
}

doc_data equals NULL.  I've tried tracing it back, but I can't tell
how the NULL enters the picture.

Nisheeth, do you handle the parser as well? If not reassign.
