Leaks with XalanTransformer and external functions
--------------------------------------------------

                 Key: XALANC-697
                 URL: https://issues.apache.org/jira/browse/XALANC-697
             Project: XalanC
          Issue Type: Bug
          Components: XalanC
    Affects Versions: 1.10
         Environment: Win32 MSVC6
            Reporter: ivan


See XalanTransformer::uninstallExternalFunction cleans up first and second of 
the m_functionPairs element, while XalanTransformer's destructor only cleans up 
second. If you don't uninstallExternalFunction and delete the transformer you 
have a leak.

Also, the Apache samples on extension functions 

http://xml.apache.org/xalan-c/extensions.html

present a Function::clone without parameters that does not exist; and if you 
happen to new ignoring the memory manager then the memory is not claimed by 
xalan (use the puzzling XalanCopyConstruct and Xalan does claim it).
