Dear Alberto :
I use xerces for parsing XML String , I found some
question in my test
platform : IBM AIX 5.2
complier : IBM VA C++
xerces version : 2-8-0
Q1. xerces can support multi-thread ? ( I found answer in
xerces faq from http://xerces.apache.org/xerces-c/faq-parse-3.html#faq-6 )
need you double confirm
Q2. In my function , always core dump in ( new
MemBufInputSource )
I use C++ while function for test xerces have memory
leak
Q3. If I use C++ delete function delete xerces object ,
why xerces still have memory leak ?
Q4. MemBufInputSource have limit usage ?
attach file is my function
