For me the problem remains as long as there are substrings of attrlist.
Probable culprit: r16-1096-gafa2de8093a0cd
In gfc_conv_substring:
> gfc_conv_expr_type (&start, ref->u.ss.start, gfc_charlen_type_node);
-> start.expr has type gfc_charlen_type_node
> diff = fold_build2 (MINUS_EXPR, size_type_node, start.expr,
> build_one_cst (size_type_node));
-> start.expr is used with type size_type node.
Oops.
