Actually no, you're right, this exact one is not covered and likely is
unreachable, because
error ("attribute %<%E(%s)%> missing an argument",
name, access_str);
will return earlier if there are no arguments and so the only way to have
idxnodes[0] NULL would be if there is an argument, but with NULL TREE_VALUE,
which I think isn't possible.
