--- Comment #4 from Nathan Sidwell <nathan at gcc dot gnu.org> --- Note to stage-1 me: Jason wrote: But I don't think that we need to keep saving the converted current_template_parms; diagnostics could also normalize using NULL_TREE args. And it looks like diagnose_nested_requirement isn't currently doing re-normalization anyway. This doesn't need to block the release, though.
