--- Comment #2 from Paolo Carlini <paolo.carlini at oracle dot com> ---
A few notes - I'm not sure I will actually be able to work on this, maybe
somebody like Marek wants to beat me to it.
If in build_over_call we unconditionally return error_mark_node when mark_used
returns false we avoid the ICE. Then, however, we have duplicate diagnostics,
because we already emitted the second error while trying to parse a class
member access, but when cp_parser_postfix_expression returns error_mark_node in
cp_parser_decltype_expr we don't set id_expression_or_member_access_p and try a
full expression too.
