re PR fortran/57284 ([OOP] ICE with find_array_spec for polymorphic arrays)
2019-04-22 Paul Thomas <pault@gcc.gnu.org> PR fortran/57284 * resolve.c (find_array_spec): If this is a class expression and the symbol and component array specs are the same, this is not an error. *trans-intrinsic.c (gfc_conv_intrinsic_size): If a class symbol argument, has no namespace, it has come from the interface mapping and the _data component must be accessed directly. 2019-04-22 Paul Thomas <pault@gcc.gnu.org> PR fortran/57284 * gfortran.dg/class_70.f03 From-SVN: r270489
