It says the XML file is missing end tag.
The root cause of this issue is before passing the XML to XML
parser, federation server needs to get the soap response header,
and the header and the body is sending back together from remote
web service. While getting the response header, federation
server uses the same buffer to store the soap response and uses
"memcpy" to move the buffer content. While moving the content
the destination address and source address can overlap, and this
leads to some undefined behavior.
The correct usage should be "memmove". |
