    * trans-stmt.c (gfc_trans_allocate): Before the pointer
    assignment to transfer the source _vptr to a class allocate
    expression, the final class reference should be exposed. The
    tail that includes the _data and array references is stored.
    This reduced expression is transferred to 'lhs' and the _vptr
    added. Then the tail is restored to the allocate expression.
