Hi Boris,

thanks for your immediate response and sorry for my delayed answer.

In the meantime, I could fix my problem easily. It turned out that we 
had unnecessary java-like initializations of local variables in the user 
code, for example

   xml::journal_paggr jpaggr
      = xml::journal_paggr();
   xml::document_pimpl doc_p
      = xml::document_pimpl doc_p(
           jpaggr.root_parser(), jpaggr.root_name());

that seem to rely on auto-generated constructors and assignment 
operators. No problem for the old msvc 2010 compiler but obviously for 
gcc that implements the C++11 rules for automatic generation of 
constructors and assignment operators (if enabled).

For a future release it might be helpful to decide whether you want to 
support this kind of copy & assignment - or you could explicitly forbit 
it by making the relevant constructors and operators private.

Thanks again for help!


Best regards
Markus
