[Trilinos-Users] Problems with Teuchos::XMLObject memory management?

Hi all,

I'm trying to put together a fairly complicated XML structure to be used 
as the 'light-weight' part of an Xdmf output format. All goes well until 
the end of the run, when the XMLObject is being deleted, whereupon I get 
a coredump. It seems that there is an issue with the internal 
std::vector destructor.
When I put everything in one main program it works, I suspect it has to 
do with the way new XMLObjects are copied into the vector. I noticed 
that there is a method 'deepCopy', but no copy constructor, which might 
explain the behaviour (std::vector push_back calls the copy constructor).
Am I doing something wrong? I'm surprised it works for the 
XMLParameterListWriter class. Is there an example somewhere?
By the way, I'm working with Trilinos version 8.0.1

thanks for your help,
