    * trans-expr.c (gfc_trans_assignment_1): If the rhs is an op
    expr and is assigned to a deferred character length scalar,
    make sure that the function is called before reallocation,
    so that the length is available. Include procedure pointer
    and procedure pointer component rhs as well.
