--- Comment #2 from seurer at gcc dot gnu.org ---
With a bit of hacking with a chainsaw I got it to this:


#include <vector>
#include <memory>

class SparsityPattern
{
  public:
};

template <class SparsityPatternBase>
class BlockSparsityPatternBase// : public Subscriptor
{
};

class BlockSparsityPattern :  public BlockSparsityPatternBase<SparsityPattern>
{
};


class MGTransferBlockBase
{
  public:
    std::vector<std::shared_ptr<BlockSparsityPattern> >
prolongation_sparsities;
    template <int dim, int spacedim>
    void build_matrices ();
};

template <int dim, int spacedim>
void MGTransferBlockBase::build_matrices ()
{
  prolongation_sparsities.push_back (std::shared_ptr<BlockSparsityPattern> (new
BlockSparsityPattern));
}
