+ Hy there,
+ 
+ while testing my application that uses your great Xerces-C++ library I found a
+ really critical Memory-Leak (in my opinion). It is in the class DOMString when I
+ use the transcode() method. You can easily reproduce it with this little
+ program:
+ 
+ 
+ #include <iostream.h>
+ #include <util/PlatformUtils.hpp>
+ #include <dom/DOMString.hpp>
+ 
+ int main(int argc, char *argv[])
+ {
+ 
+   try
+   {
+     XMLPlatformUtils::Initialize();
+   }
+   catch(const XMLException& toCatch)
+   {
+     cerr << "Error while initializing Xerces-c library!" << endl;
+     exit(1);
+   }
+ 
+   DOMString TestString = "test";
+ 
+   for(int i=0 ; i<10000000 ; i++)
+   {
+     TestString.transcode();
+   }
+ 
+   return(0);
+ }
+ 
+ 
+ Memory-Usage increases VERY fast when you start the Program. While debugging the
+ library I found the responsible code.
+ It is this line in the transcode() method:
+ 
+ char *retP = new char[charsNeeded + 1];
+ 
+ The variable retP is the Return-Value of the method. The allocated memory is
+ never freed when you do it this way. retP maybe should become a class-member to
+ avoid this.
+ 
+ I hope, you find a way to fix this bug. Please let me know, what could be done
+ and when the fix is finished.
