revision-id: knielsen@knielsen-hq.org-20130816131025-etjrvmfvupsjzq83

revno: 3674

branch-nick: 10.0-base

Built with BUILD/compile-pentium-valgrind-max-no-ndb

Also reproducible on the current 10.0 tree. Could not reproduce on 5.5.

It might turn out to be a duplicate of some other valgrind warnings filed recently, but I haven't had this stack trace yet, so submitting it to be on the safe side.
