Segmentation fault with xqillia when using purifyplus

Question

Hi friends,
I am using BDB , xqilla /xerces interface to perform an xquery.The program works fine,but after building the program along with purifyplus,if i try to run the program a segmentation fault is raised.
attached are the code,command used to build the program and the stack trace.
here is some specifications-
Rational Purifyplus 7.0
gcc version 3.4.6
OS-Linux(redhat);Linux 3 2.6.9-89.ELsmp
dbxml-2.4.16
CODE:
#include "DbXml.hpp"
#include <iostream>
using namespace DbXml;
using namespace std;
int putxml(string filename,string docname2)
XmlManager myManager;
XmlContainer myContainer;
try
if (!myManager.existsContainer("Container.bdbxml"))
myContainer =myManager.createContainer("Container.bdbxml");
myContainer = myManager.openContainer("Container.bdbxml");
XmlUpdateContext theContext = myManager.createUpdateContext();
XmlInputStream *theStream =myManager.createLocalFileInputStream(filename);
myContainer.putDocument(docname2,theStream,theContext,0);
catch(XmlException &e)
cout<<e.what()<<endl;
/* function to get the xml file and display output */
void getxml(string docname3)
string query_result;
try
XmlManager myManager;
XmlContainer myContainer = myManager.openContainer("Container.bdbxml");
XmlQueryContext myContext = myManager.createQueryContext();
myContext.setDefaultCollection("./Container.bdbxml");
cout<<"docname3 is "<<docname3<<endl;
std::string myQuery="for $i in doc('dbxml:/Container.bdbxml/docname') return ($i)";
XmlQueryExpression qe = myManager.prepare(myQuery, myContext);
XmlResults results = qe.execute(myContext);
XmlValue my_value;
while (results.next(my_value))
query_result += my_value.asString(); //xml file data come in query_result
}catch(XmlException &e){
cout<<e.what()<<endl;
cout<<query_result<<endl;
/* main function */
int main()
string filename("XYZ.xml"),docname1("docname");
putxml(filename,docname1);
getxml(docname1);

As per my understanding my program is crashing in XQParser::yyparse(void*) which is in YACC. is there any known issue regarding compatibility between YACC and Purifyplus ?
Kindly help me out
Thanks.
