Public bug reported:

There is a memory leak in

%typemap (in) CONST_VECTOR std::vector<CONST dolfin::TYPE *>
&(std::vector<CONST dolfin::TYPE *> tmp_vec)

which is due to mixed-up ownership. For example, for the coefficients
passed through this interface from the Python Form constructor to the
cpp Form constructor, their destructor is never called.
