writeToString return value

[de...@oget.net]

What is the status of XMLCh* returned by a DocumentWriter, in terms of
memory management? Should the ressources be freed by a call to
XMLString::release or will the DocumentWriter take care of it when it is
released?

When I used XMLString::release on the return value valgrind complains that
it is using delete[] instead of delete:

Thank you for the help
