Hi Sasikumar,
you must be doing something wrong in the destructor; could you post
the code? Otherwise it's just a guessing game...

As per Alberto's suggestion, I moved Initialize/Terminate of both
XMLPlatformUtils and XPathEvaluator to main function. But still I am
getting crash.
And if didn't call destructor(i.e., without using delete) of my class
"XMResponseParser" which internally has SAXParser object, then it is
working fine. Without deleting the memory of the object, I am creating
new object for the next request.
But above scenario will lead to memory leak. Kindly give me the
suggestion why it is happening as above?

Subject: RE: Getting core dump at xerces::SAXParser::parse function
Hi Alberto,
Thanks for the information. I will verify the system after moving the
Initialize/Terminate to main.
And one more question is "I am creating SAXParse for every xml response
and end of validation, I am deleting the memory. Is that correct way of
doing it?"
Thanks & Regards,

As the crash in inside the memory manager, it could be that you called
Terminate and then Initialize while still keeping some objects alive.
Please move the Initialize/Terminate calls to the "main"
function and call them just once.
