This is apparently caused by the following two implicit conversion
operators that are defined in the fundamental_base class template
(libxsd/xsd/cxx/tree/elements.hxx:1235):

template <typename Y>
operator Y () const
{
  return x_;
}

template <typename Y>
operator Y ()
{
  return x_;
}

They were disabled for 7.1 because they cause ICE to this compiler.
Since they are rarely used we have disabled them by default in the
next release. You can also comment them out in your copy of XSD as
a work around.

Thanks for reporting this!

Boris
