My gut tells me it's more likely to be Zack's unused-declaration stuff
or the SAVE_EXPR rewalk avoidance stuff we collaborated on -- but
there's no telling.  It would be great if you could get a smaller
example; that does usually help a lot with these cases becuase you're
often trying to figure out what's going on in a large piece of tree
structure.  Would you mind doing that?  Just send me the stripped down
case privately, and I'll take a look.

Thanks!
