Doesn't ICE in release mode.
In general, we have an issue with <void> as non-type parameter: when we see it,
we of course error out, we store an error_mark_node and go ahead normally. Then
the error_mark_node can come out in many different places: lots of ICEs, all
ultimately due to the same issue.
