SF Bug Tracker id 3175217 - Crash bug in Parser_addNamespace()

Browse Source 
Submitted: Terry Farnham ( tfarnham ) - 2011-02-07 09:25:25 PST

Details: The strcmp(pNode->prefix,pCur->prefix) crashes on pCur->prefix
being NULL. This occurs on invalidly formatted xml where a node uses an
undefined namespace. I would expect to receive IXML_FAILED in this
situation.
