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