Xerces-C 2.1.0 - core in XMLReaderFactory::createXMLReader().

["Tarkus, Anand (LNG-DAY)" <an...@lexisnexis.com>]

Hi,
We use the Xerces-C version 2.1.0 in our multithreaded application. This
application creates around 100 threads with each thread creating 2 instances
of the SAX2XMLReader. 
It seems the XMLReaderFactory::createXMLReader() is not multi thread safe,
it dumps core.

stack trace using dbx:

  [1] pthread_mutex_lock(0x0, 0x0, 0xc3474, 0xfe941cbc, 0xff1a1660,

any ideas...?

Thanks,
Anand.
