Hi all,
I have re-engineered a VC++(6) application to a multithreaded design and now
find that calls to xerces functions (v1.5) crash.
The thread sits and monitors a directory for XML file and then creates an
object (CStateMachine) to process the file (the file is represented as a
CDataFile object in the code below).
The first XML file collected and processed seams to work, then the
(CStateMachine) object is destoryed, but when the second attempt is made to
create the object, the application crashs when it goes to creae a new
SAXParser object.
Am I doing something wrong ???

pLog->log_function("CommandProcess(CDataFile)");

{
cout<<"Error during initialization! - "<<toCatch.getMessage()<<endl;
pLog->log("ERROR - Unable to initialize XML sub system");
return false;

);

}
