Description:
Hi,

I think we have found a problem with XMLReaderFactory::createXMLReader on 
Tru64. We have a multithreaded environment (actually in this test case there 
are two threads). While one thread is waiting, the other thread tries to create 
a parser. The test core dumps with the following trace :

Note that the other thread is off waiting elsewhere and does not use, create or 
interact in any way with xerces. The code is quite simple : 

    m_parser = XMLReaderFactory::createXMLReader();

Any help on this would be extremely grateful.
