PR fortran/87566
* resolve.c (resolve_assoc_var): Add missing array spec for
class associate names.
(resolve_select_type): Handle case where last typed component
of the selector has a different type to the expression.
* trans-expr.c (gfc_find_and_cut_at_last_class_ref): Replace
call to gfc_expr_to_initialize with call to gfc_copy_expr.
(gfc_conv_class_to_class): Guard assignment to 'len' field
against case where zero constant is supplied.
