--- Comment #5 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
In finish_class_member_access_expr we have
expr = build_class_member_access_expr (object, member, access_path,
/*preserve_reference=*/false,
complain);
if (processing_template_decl && expr != error_mark_node)
{
if (BASELINK_P (member))
{
if (TREE_CODE (orig_name) == SCOPE_REF)
BASELINK_QUALIFIED_P (member) = 1;
orig_name = member;
}
return build_min_non_dep (COMPONENT_REF, expr,
orig_object, orig_name,
NULL_TREE);
build_class_member_access_expr builds a component_ref that seems to be ok; its
arg1 is a field_decl. But the subsequent build_min_non_dep call changes this
field_decl into ORIG_NAME, which is an identifier_node.
