--- Comment #8 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-10-26 23:38:33 UTC --- I think that at some point I had the same trick in my local tree too, then I don't remember sending it to the mailing list, not even as a RFC. I think you should, CC Jason, and ask whether is it possible that at that point TREE_TYPE is not set or the check would just paper over the real issue.
