The issue seems to only occur with scalars.

Generated code

  a = *bar ();

Expected: One uses a temporary as in

  tmp = bar ();
  a = *tmp;
  free (tmp);

The same issue occurs with reallocate LHS, were also a temporary should be
used.

[Check that the allocation/freeing is properly done for variables with length
type parameter (currently only deferred-length CHARACTER strings).]
